It's not uncommon to experience valve float with the OEM valve springs, even below the OEM rev limit. On some applications like the 2.0 TSI, backpressure from the K04 turbocharger has been known to force the exhaust valves open. This has been noticed on vehicles with overly weak OEM valve springs and some with higher miles that have simply lost their stiffness over time.
This issue accompanies misfires commonly above 5000 RPM. In some extreme cases, valves are forced open and the vehicle ceases accelerating any further. A quick datalog of intake mass airflow and boost pressure at wide open throttle will show a sudden rise in boost pressure with an immediate loss of airflow as pressure from the open valves is pushed back into the intake manifold.
On other applications, valve float can begin to occur just beyond the OEM rev limit. While other components, such as higher strength valves are often required for extremely high revving applications, the APR Valve Spring System will eliminate float well beyond the revving constraints set forth by the other components.
APR is pleased to present the APR Valve Spring System.
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 Golf R setup and is proven to eliminate the OEM valve train's weakest link. We call it Performance Without Compromise!

Awesome GTI Delivery Information
Do we ship abroad ?
Yes we do, to anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UKMail so you can track the package online and could reach america within 48 hours providing its in stock !
There are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Yugoslavia, Romania, Croatia, Hungary, Slovakia, Slovenia, Russia, Nigeria, Macedonia, Singapore, Bulgaria, Ukraine, Lebanon and Lithuania.
Why is postage on bulky items to some countries expensive compared to some other companies ?
For both yours and our safety we use well known couriers such as UKMail for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
