About Air Filters
Looking to get a little more power and better fuel economy from your Plymouth Valiant? Upgrade your air filter! Stock filters can often be inefficient and restrictive, limiting the performance of your engine. A performance air filter from NAPA Auto Parts provides your engine with high quantities of clean air, resulting in increased horsepower and torque as well as improvements in fuel economy. Dust and other particles are blocked from entering, meaning the engine is kept cleaner for longer. It's a simple upgrade that makes a big difference - so don't wait any longer!
