K&N Intake
By Michael S Miller
Easy to install and works very well. Replaced a different brand with the K&N and will only use K&N kits from now on. Filter is bigger, kit is better quality, and over all better product. Improves gas milage and performance.

i bought k&n for several reasons, best price is on amazon, add performance, reusable air filter, and it's K&N. Plus I got it sooner than I was expecting.

So far so good!
By Michael Mcgowan
I am writing the review prematurely on purpose so I can relate initial impressions and observations, then add to it later with more information as time goes by.To begin with, I highly, strongly encourage those who like to do things by the seat of their pants and refer to the instruction only in cases of getting stuck to RTFM before you start even if you are a self proclaimed 5 star back yard mechanic. Reason for this is so you can identify discrepancies in the installation steps before you get into it rather than after and have to stop and do some R&D to continue.That said, the installation on my 2002 Impala LS went off pretty much without a hitch, save for the ground strap stud that snapped and had to be drilled out before I continued, and the fact that I still haven't compensated for the intake elbow bracket not fitting to the indicated location on my transmission properly. (minor detail)It took me about 2 hours all told being as that I was going step by step and being very cautious. (and that was not counting messing around with the uncooperative rubber strips and messing around with jockying the plates around to get them to fit properly... which they did)After install completion, my initial observations are: much louder sucking sound upon cold start until rpm's settle down. No biggie. Snappier throttle response, be forewarned, you just think about the car moving and it does before you know it!Biggest initial obs. is the fact that prior to installing, whenever I'd park the car after arriving at work, or home from work (22 miles one way) popping the hood was like opening a fully stoked boiler on a coal burning freight train. It was always hot enough under the hood to bake potatoes! Now, I can pop the hood and touch any part under there and not get burned... no blast of heat smacking me in the face like a kitchen broiler. And the intake elbow tube, despite being black, is actually COOL, yes I said COOL to the touch.I can only imagine how much cooler the intake air is, and thusly how much more dense and efficient it's making the engine run.I'm not a hot rodder, but as time goes on I will report on mileage and performance as I gather the data.For comparison sake, currently I get just under 27mpg (combo hwy/cty) and that was up from 24-25 when I changed to a FRAM airhog filter and removed the intake "muffler" tube. I can already see halfway through this tank of gas that I've gotten more miles per needle position than normal, but I'll wait until another full tank passes to post the actual numbers.So far, so good!(Oh, and PS: at the same time I also went from a single stock muffler to dual flowmaster super 44's, so some of this may be attributed to that, but I highly doubt it as mufflers are more for sound that performance in this car's case)
