Product Details

Valve Spring Kit (MS100258) by APR®. 1 Set. The APR Valve Spring System is a high performance, lightweight upgrade designed to increase valve control and eradicate valve float common on many applications. APR's design specifications called for a valve spring, retainer and spring seat combination that doesn't overpower and snap the OEM valves or erode the aluminum spring seat, while still maintaining exceptional valve control. The result is an advanced design that's 28% lighter yet 20% stiffer than the high performance OEM EA113.K04 (MK6 R) setup and is proven to eliminate the OEM valve train's weakest link. We call it Performance Without Compromise!

It Does Work! So Glad I’ve Picked It)

I’ve read this system should increase valve train control but I wasn’t expecting much. You know, I rarely feel those performance benefits aftermarket manufacturers promise. But I was lucky this time. This kit does its job perfectly. And the valves are lighter than my stock ones but feel so durable. Worth every buck paid!
