Speaking of filters , where would the K&N filter rate among the other and the others mentioned earlier in thread?
The Pentastar Upgrade, or PUG, is in the Grand Cherokee and new Wrangler. Those engines, at least initially, were sourced from Mexico. I say originally, because there was rumor of problems causing them to switch to engines made in the US factory, but I think the rumor is [censored] for several reasons, first being that the US factory, to my knowledge, has not begun to produce the PUG yet, but still makes the "old" Pentastar. The other reason is that I have a Mexican built PUG in my JL and it has been flawless, so far.
