K&N has developed an air intake system, part number 69-8005TWR for the 2008 to 2014 Subaru Impreza WRX STi with a 2.5 liter engine. K&N dynamometer testing shows an amazing 17.52 horsepower gain at 5260 rpm.

The 69-8005TWR features an aluminum intake tube with a powder coated wrinkle red finish and a K&N carbon fiber top cone shaped universal air filter, part number RP-5113.

The K&N washable and reusable air filter is isolated by a heat shield to help direct fresh outside air to the engine. The filter captures harmful particles, provides low restriction and also increases filter service life compared to the OEM air filter.

It will perform for up to 100,000 miles before service is required depending on driving conditions.

The impressive horsepower gain is also aided by the radius adaptor’s design as it smoothly takes the 5 inch flange of the air filter and connects it with the intake tube.

The high-flow technology invented by K&N provides a great balance of airflow and filtration. Designed to be installed with simple hand tools in 90 minutes or less, this K&N air intake system is backed by the K&N Million Mile Limited Warranty.

Gary Scelzi Motorsports' Dominic and Giovanni Nearly Unstoppable at Lemoore Raceway

Around the neighborhood, Dominic and Giovanni Scelzi look just like a couple of regular kids, the kind that tool around on BMX bikes, or rock the streets on skateboards. Put them on a track though, behind the wheel of a racecar, and they've been known to bring tears to grown men's eyes.
Portrait of a family racing destiny for years to come, Dominic, Giovanni and Gary Scelzi
Portrait of a family racing destiny for years to come, Dominic, Giovanni and Gary Scelzi


Dominic "The Dominator" and Giovanni "Hot Sauce" Scelzi were born to be racecar drivers. It's in their blood and in the air they breathe each day. Their father is four-time NHRA Drag Racing Champion Gary Scelzi, from Fresno, California. Although his exploits and accomplishments in both Top Fuel and Funny Cars are the stuff of legends, he would rather not talk about that just now, preferring rather to keep the spotlight where it currently and rightly belongs – on his two remarkable sons. Gary is having far too much fun witnessing racing from Dominic and Gios' perspective, as though viewing Disneyland all over again through a child's eyes.

Dominic is the older brother and drives in the Super 600 Class now. He was told guys in their 20 and 30's are never going to move over when a 12 year-old kid tries to pass them. Yet, it only took Dominic four races to win his first Super 600 race in Lemoore, California earlier this year.

Giovanni, unlike Dominic, never raced go-carts or anything else until he got into a Jr. Sprint car. He won his first race at age six. Gio won't turn nine until November and even though everyone considers him mentally ready to race Restricted 600's, the official age limit is ten.

Last weekend Scelzi Motorsports returned to Lemoore Raceway and Gio was ready to add to his winning streak of five consecutive wins going into the event. In his first heat race he crossed the finish line with more than half a lap lead on the second place car. He won his second heat race as well.

"The Main event was like no other main we have ever experienced," commented Gio's crew chief Frank Potter after the race. The track had become very rough and turned into a huge challenge for the Jr. Sprints. There were an unusual number of mishaps and cars flipping during the race. Gio got wrapped into one crash while attempting to take the lead. This put him at the back of the pack for the restart. Even with a badly damaged right front wheel, Gio was steadily working his way back to the front when track officials cut the race short to only 11 of the scheduled 20 laps. Giovanni finished fifth and was upset that he didn't have all the laps to work himself back into winning his sixth straight race.

Dominic was on a mission going into the race as well. He had a couple mishaps at the last two main events at Lemoore and was determined to rectify that. He won his first heat race with a dramatic lap seven pass on the leader. In the second heat race, working hard to stay away from the roughest parts of the racetrack, Dominic played it smart and did a great job finishing fourth.

With the win and fourth place heat finishes, Dominic started the 30 lap Main Event in second. At the green flag Dominic jumped out into the lead and held it for 16 laps, at times several car lengths in front of the second place car. The leaders got into lapped traffic though and Dominic did a great job working his way through the traffic, swapping places with the pole setter for most of the race.

They continued working through lapped traffic until the yellow flag came out with eight laps to go. On the restart Dominic was in second, ultimately staying with the lead car for a second place finish. "Considering the rough track conditions and the great competition, Dominic did an outstanding job, we are all very proud of him," remarked his proud father.

Midwest All Star Champion Jerrod Hull is Back on Top of Sprint Invader Association

For years the Sikeston, Missouri native Jerrod Hull was top-dog, the winningest driver in the Sprint Invader Association, then for a blink he fell off. But, when the checkered-flag waved at the familiar grounds of Southeast Iowa's 34 Raceway recently for the season opener, Hull was back.

"It feels real good to be back at the top with the Sprint Invaders," commented the three-time Midwest All Star Champion. "We don't get to run the series as much as we would really like to because of our scheduling conflicts. My team primarily is from the Burlington, Iowa area, which is the same area the Sprint Invaders typically run their events, so anytime we win, it's like we are winning in front of a hometown crowd. To get to 13 wins with the limited schedule we run with them is a true testament to this team."

To clarify, Hull runs a typical "Outlaw" style season, meaning he doesn't commit to any one series or track for a full season. In sprint car racing there are a number of different sanctioning bodies, tracks and classes racers can compete in. Hull runs 410 Sprints and 360 Sprints, the Sprint Invader Association covering the latter of the two. Hull is a three-time Champion with the Midwest All Star Series, which is a 410 Sprint Car series.

Since the inception of the Sprint Invader Association back in 2002, Hull has competed with them 40 times, but he's never run a full season due to scheduling conflicts. Out of those 40 times Hull has earned 13 victories, 25 top-three finishes, and 33 top-tens. In 2005, while running the same limited schedule, Hull ran in eight events, winning six, and was named Driver of the Year.

Hull is also fast to give credit to members of his Jerrod Hull Motorsports team and his product sponsors. "I am very pleased with the partnership we have with K&N Filters," says Hull.

"A couple of years ago in the offseason, I was looking to make some changes in the approach to how we could get more advertisers excited about partnering with my team. What we came up with is a unique approach that focuses on trying to give back more than we get from the supporter. Whether it is handing out flyers, talking to other car owners about products, or even just wearing logoed apparel, we strive to make sure that when the season is over our supporters come knock on our door to come back with us."

"Currently we are using the K&N Filter Box with all of the supplies it takes to maintain the filters, as well as the K&N Wrench-off Oil Filters. Bottom line is, K&N products provides my team with the competitive advantage we need to make it to victory lane, it is race proven week after week."

"Our current plans for the season are to continue our formula of success," remarks a confident Hull.

"We are looking to make it four Championships in a row with the Midwest All Star Series, as well as hitting some additional Midwest events in Iowa, Illinois, Missouri, Arkansas, Wisconsin, and many other local areas. Up next for us is the first Midwest All Star event of the year, which will be co-sanctioned with the Interstate Racing Association (IRA), at Charter Raceway Park in Beaver Dam, Wisconsin."

Holmes won for the first time at Phoenix International Raceway in the race on April 8. It was the 10th win of his West Series career.

The win moved the two-time West Series champ into third place in the West Series standings.

"We needed it bad," Holmes said of the Phoenix win. "We had a bad day at All American Speedway (Roseville). We came here to win the race and get the most points and we did that. So, now we'll move on to the next race and try to do the same thing."

Holmes crashed and finished 20th in the opening night race in Roseville. It was not the way he wanted to start the 2010 West Series season.

Holmes started the Phoenix race on the outside of row one, but didn't take the lead in the race until lap 47 of the Jimmie Johnson Foundation 100.

Andrew Myers won the pole for the race. He led the first nine laps of the race. Greg Pursley took over on lap 10 and led for the next 22 laps. Then it was David Mayhew's turn to take the lead. He held the top spot for 13 laps before Holmes took over.

Brett Moffitt got the lead on lap 52 and again on lap 62. He led the most laps in the race, but spun out on lap 88 and dropped out of contention.

Pursley led for four more laps before Holmes took back the lead on lap 93 and led the rest of the way, surviving a crash on lap 98 that took out three cars. Brett Thompson, Kyle Kelley and Brian Wong were collected in the crash.

"Those guys were racing hard and got together and it got us back to second and we got a great restart," said Holmes, a driver from Escalon, Calif., and for Bill McAnally Racing. "We thought we had it won, but got another caution for a green-white-checkered. I got a good restart."

The race ended under caution after a four-car crash in lap 104. Auggie Vidovich, Moses Smith, Josh Combs and Luis Martinez Jr. were collected in the last-lap crash.

"I've wanted to win a race here for quite some time," said Holmes. "We had a good car all day. I just saved it for the end. The NAPA team did a great job on the last pit stop making the call. We had some great restarts at the end and got us the win."

Jason Bowles, the 2009 West Series champion, was second, followed by Pursley in third. Pursley and Mayhew are tied for the leaed in the West Series standings with 320 points. Holmes is in third, 32 points out of first.

"This was a big picture race for us and as much as I wanted to win, finishing third is a great night," said Pursley, a driver for Gene Price Motorsports. "We had a lot of concern about the engine but the thing never missed a beat. This whole Gene Price Motorsports team does a fantastic job and Jerry (Pitts) made great calls and had a set up that was perfect. This was a fun car to drive."

The next race for the West Series is at Iowa Speedway on May 23. It will pit drivers from the West and East series against each other.
