The K&N is another one that you will get several opinions on. They flow more air by not filtering as small of particle as a paper filter, and they also require routine maintenance. When we ran the late model down at the local oval track, yeah we had one on the small block, but we were turning close to 7 grand. It may have made a difference at that RPM, but we never had the car on a dyno to know for sure. I have never and will never run one on any of my street rigs, give me a Wix or a Napa Gold any day over and oiled filter. I had a few buddies that ran them and they were always have problems with sensors in the intake getting fouled, and their oil always seemed to get dirty sooner, but these are just my casual observations, nothing scientific. Your engine stock is around 190 HP 210 ft-lb of torque, itÆll do you quite well, quite a bit more than a 22RE, which I had one of too, but in an Æ85 Celica.

Yours should have 3.55 gears in it, I wouldnÆt think that should be too bad with 31Æs on it, but I am basing this on my manual trans with the 3.07 gears, so I could be a bit off compared to the Auto. I wouldnÆt mind having 3.55Æs in mine so I could go to 31Æs but IÆll cross that bridge later on.

Oh, one other thing I would check out is the weather strip, mine looked fine, but it was leaking in through the rear hatch and all the screws, bolts and nuts that attached to the floor on the inside even up front were rusty.
