Oh yea I bought mine off of viva performance. Thought it would help regulate heat better and help me not crack a block. Fingers crossedWell theres 2 kinds. The RS oil cooler has oil and water fittings that only fit the RNC cars. The "D5" oil cooler is what the P2 chassis cars can take because they have different fittings that originally came on diesel cars only for obvious reasons. Just take a look at the different in fittings between the RNC oil cooler and the RN D5 oil cooler that the P2 cars take. The difference is almost 100% in the style and angle of fittings. I'm fairly certain they're identical otherwise.
