Part#: 311-05-7350 (B-Series VTEC Pro Series XP Racing Valve Spring Kit)
Part#: 311-05-7380 (K-Series i-VTEC Pro Series XP Racing Valve Spring Kit)

Skunk2 is proud to introduce its Pro Series XP (Extra Pressure) Racing Valve Spring Kits for Honda’s B-series VTEC and K-series i-VTEC engines. 

“XP” features a higher seat pressure for turbocharged and extreme high RPM motors. This spring has a seat pressure of 100lbs @ 1.600” for the K-Series and 93lbs @ 1.320” for the B-Series engines while keeping the coil bind height for higher lift camshafts.

By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Pro Series XP Racing Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 11,000 rpm.

Motovicity's Sean Grogan tunes his FR-S to win back-to-back racing events

There's a modest look about MotoRep Sean Grogan that downplays the winning streak he's had for the start of the 2013 SCCA race season. But if there's a regional SCCA sports car driver that's on the top of his game, it's Grogan.

Two weeks ago he swept the SCCA Spec Neon class at Waterford Hills. Last weekend he bested 140 locals at the Detroit Region SCCA season opener, where he took the top spot in his #86 2013 Scion FR-S in the Pro RTR C-stock class and placed top overall.

Grogan's best run was a 50.550 lap, giving him a PAX index time of 41.097 to lead the field and place him sixth overall for raw time. He was last year's 2012 SCCA Pro class champion driving a 1997 Neon ACR.

Ironically, he purchased his FR-S the same day Motovicity bought the Ticket-to-Ride FR-S they're giving away in September. His goal was to quickly get it ready for the Road Tire/Rear-Wheel-Drive SOLO class to startMore...

As a company built on providing rugged, lightweight high-performance radiators as the core of its business, Mishimoto also offers a line of intercoolers that utilize their precision TIG welded 6061 aluminum construction. 

Their universal intercoolers provide ideal cooling capacity with minimal pressure drop, from their low profile Z-Line measuring 28"W x 7.5"H x 2.5"D to the full size G-Line measuring 24.5"W x 11.75"H x 3"D, which can handle up to 32psi of boost @ 1,250 CFM.

All Mishimoto universal intercoolers come with threaded universal mounting points (except the J-line) and inlet/outlet dimensions ranging from 2" to 3" depending on the line.  Mishimoto's intercoolers come in either raw aluminum or a black coated finish. They also offer the 'M-Line Eat Sleep Race Edition' with gold powder coated end tanks and silver aluminum core. 

Mishimoto also offers plug-and-play intercooler kit configurations for the Hyundai Genesis and Mitsubishi Lancer. The Hyundai kits include custom mandrel bent tubing, couplers and mounting hardware. The Lancer kits have custom fabricated inlets designed specifically for the installation.

As with every other Mishimoto radiator and cooling product, a serial number denotes the Mishimoto Lifetime Warranty, which not only covers manufacturer defects but also if the product is damaged in an accident.

It is 'cool' that Mishimoto offers an extensive line of radiators and intercoolers, but none of that matters if what connects those products to the rest of the system is sub par. 

It's like putting a used set of Fuzion all-season tires on a GT-R. You just don't do it. And further, it defeats the whole purpose. 

That same logic applies to hoses and couplers that connect radiators, oil coolers and intercoolers to high performance engines.

It's the harsh environments of street performance and race engines where traditional rubber doesn't hold up; and it's where Mishimoto has developed an extensive line of silicone radiator hoses and couplers to connect their core cooling products to the rest of the system. 

Mishimoto hoses are manufactured with dual-layer, 100% high-grade silicone and embedded heat-resistant fibers. The results are hoses and couplers with increased pressure capacity, lasting performance amid high-temperatures and efficient heat reduction

Plus, Mishimoto backs them up with their renowned lifetime warranty, which includes accident protection. If they're damaged due to an accident, Mishimoto replaces them free of charge. 

Add aesthetics to the performance attributes of Mishimoto silicone hoses. They come in a three colors: red, blue and black, and limited edition Mishimoto orange. 

There are literally hundreds of hose kits and combinations for nearly every major OE manufacturer including Honda, Toyota, Subaru, Mazda, Mitsubishi, BMW, Audi, GM/Ford/Dodge - and a wide variety of universal hoses and fittings.
