In the realm of performance engines, valve adjustments are an essential part of keeping your car running its best. When you add customization to the mix, valve timing becomes even more critical, and it’s important the technician adjusting them really knows their stuff. At Harold's Used Auto Parts Inc in Philadelphia, PA, we’ve got you covered.

On many modern engines, valves are self-adjusting and don’t require regular maintenance. On all other engines, and for custom applications, correct valve specifications are the difference between a car that runs and a car that runs well. Your valves affect compression, fuel consumption, air intake, exhaust expulsion, carbon production, and so on. If the timing and duration aren’t exactly where it should be, your engine isn’t performing its best.

Particularly on precision-engineered vehicles, valve operation is everything. Whether you need your valves adjusted to adapt to a performance build, or simply need them restored back to OE specifications, a valve adjustment will make a dramatic difference in the way your car runs and performs.

Whether you drive a BMW, Mercedes, Subaru, Jaguar, Porsche, or any other high-end vehicle, our technicians at Harold's Used Auto Parts Inc have your back. We specialize in import and aftermarket vehicles, including performance builds and tunes.
