APR Product Description
The APR Valve Spring System is a high performance, a lightweight upgrade designed to increase valve control and eradicate valve float common in 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 Golf R setup and is proven to eliminate the OEM valve train’s weakest link. We call it Performance Without Compromise!
APR's core philosophy of Innovation, Integrity, and Excellence aligns perfectly with E1 Motorsports core values. Our shared commitment to provide the highest quality and most highly engineered aftermarket performance products available for Porsche, Audi and Volkswagen vehicles.
