No. Stock intake is more than adequate for either motor option

And sucks much hotter air while filtering less.

I did the hot air intake, but only to be able to fit OBA, second battery, and a washer bottle under the hood.

But keeps it from hydrolocking in water puddles. Swap an engine from a hydrolock and $50 for a different filter system looks real cheap. Never noticed a power loss at all from the warmer air.

Not sure how a k&n can protect against hydrolock but a paper filter cant...well how either could in the right situation, I guess what I'm asking is what the difference is between the two in that aspect? Otherwise I used to be a fan of k&n filters till I was shown that they actually do not filter as good as a paper filter and unless you get a true cold air intake and are taking in outside air there is no benefit on that side either.

My setup prevents hydro locks by having the air come from the upper under hood area, rather than rammed into a sealed box fed by the grill. It is also 2 paper filters, not knn.

9/10 of people who hydrolock were either driving way too fast or were in way over the hood.
You can drive through water up to the headlights and not get the filter damp if you drive correctly.
All of my friends that have hydrolocked, and i have a few, were doing one of those two stupid things.

Only thing the K&N CAI will do is make a lot of noise, it does sounds great though.

This is the K&N Kit:
http://www.knfilters.com/search/prod...Prod=57-1513-1

If you do a search some other members have listed better airfilters you can replace the actual filter with.

i6 4.0 here with a rusty's short ram and K&N filter 185k on her and this helps! better mpg's and exceleration. no real noise difference unless i smash the gas and it is still quite with a deep roar. overall best money spent on a mod in my opinion for i6. as for the v8 big difference in power so cant speak to that.

I put one of those on, took it off after less than a week. No noticeable power difference, and it howled like a scalded dog. I go off road to commune with nature, not scare the $%# out of it. Stock system seems to work just fine.

Mine was water hole in the trail 6 hours from home, with no other vehicles to help me. Didn't want to get stuck, also didn't want to turn around, or go measure the depth of the water to do the math on how fast I could drive through without getting stuck or destroying my engine. 4lo wide open was the decision, blown engine was the answer.
