3.7 CAI Questions?

[ItsMeKO3]

I've got a guy willing to sell me his K&N CAI for the 3.7 for 100$. Just wanted to see what you guys think about this deal? Good price? Is it worth it for the 3.7? What are the gains? Difficulty to install? Just wondering if I should jump on this deal. Thanks guys.

Easy to install yes, good price yes, the gains you get are up for debate though.

Thats what I see reading about it right now. Well, I'll give it some thought for a few days.

I've been looking at them too. They are normally anywhere from $250 for the 63 up to $350 for the 77 that fits the 3.7 so $100 is a really good deal if its in good condition. I've read that the horsepower gains aren't "provable" but that it gives a little more power, helps the engine breath better, and gives it a nice sound. If you decide to get it take some pics after the install so I can see what mine would look like.

Will do.

CAI is something I continue to put off for my WK. Pretty widely known that the gains on them are fairly insubstantial. They do allow the engine to breathe better, but at what cost? Some of these brands allow silicates to deposit into the engine itself - which can seize up the engine. So the filter isn't doing much of it's job, and your probably replacing the oil a lot more frequently than you care to. I'd like one, yes, but I'm hesitant - I continue to debate with myself what would be the best intake for 3.7L WK/XK's.

In retrospect, it would be nice to find a knowledgeable vendor.
