Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kit for Honda’s B-series VTEC engines. Each kit includes Skunk2’s high-quality dual valve springs and race-proven titanium retainers that are the result of nearly two decades of racing and engine building experience. Each Alpha Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm. Skunk2’s industry-leading Alpha Titanium Retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Similar to Skunk2’s already popular Pro Series Titanium Retainers, Alpha Titanium Retainers feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction. Alpha Titanium Retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno as well as the race track. Once approved for manufacturing, only medical-grade titanium that’s been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures.

I’m extremely happy with these taillights
Excellent Upgrade — Completely Modernized My BMW
I’m extremely happy with these taillights. I installed them on my 2009 BMW 335xi E90, and they completely updated the appearance of the car without making it look overly modified.
The clear-smoke design looks especially good against my Space Gray paint, and the LEDs are bright, crisp, and give the rear of the car a much more modern appearance. Fitment was very good and the finished installation looks clean and close to OEM quality.
I wanted something that would modernize my older BMW while still keeping it classy, and these accomplished exactly that. They made a much bigger difference to the overall appearance than I expected.
Very pleased with the quality, fit and appearance. I would definitely recommend them to other E90 owners looking for a tasteful lighting upgrade.
