For a few extra bucks, the SRT oil filter is worth it. You can often find them for sale on E-Bay for $13.

The SRT engineers worked with many of the filter suppliers to get the best features. Some fell out for various performance reasons but they ended up developing the current SRT filters with Wix, a mainstream manufacturer.

The high flow oil pumps in our large engines (Viper is the biggest) can overpower the internal relief valve. When this valve opens it allows some of the high pressure dirty oil to bypass the filter element in order to keep the filter from being damaged. The SRT filters have a higher pressure differential bypass valve to make sure all the oil delivered to your engine, at cold starts and high demand, is clean.

The housing is also slightly thicker than many of the brands out there to handle the pressure but is not the thickest. The real thick ones tested by the SRT engineers failed their development testing (fractured at the crimped flange). The media used is one of the latest synthetics that allow for very fine filtration, more debris capacity, and much lower restriction than the standard Mopar filter and just about every other filter out there.

In addition to providing maximum protection for the street, the SRT filter is ideal for track use day where it will allow your engine to sustain proper oil pressures in extreme cornering conditions.
