On my 88 GT, the drop in helped gas mileage a little. Im sure performance went up a bit because it is less restrictive. The Weapon-r I origionally bought sucked in too much hot air sitting in the engine bay. I did feel the loss of power there. So go with a drop in unless you want to spend more for a CAI or customize it yourself!

i was pretty happy with the k&n for my LX, it gave it a little kick, without breaking the bank. just be ready to shell out $50 for it...

CAI = Cold Air Induction.
www.probesport.com sells one for our cars for about $65, it has an aluminum adapter plate that bolts to the VAF meter, and a cone filter attaches to it. I'd say on a N/A car, a K&N would make a pretty big difference, and the CAI type would make an even bigger difference. And since the K&N is gonna run about $45 anyway, might as well shell out the extra cash for the probesport CAI, and help out someone who's trying to help out the probe/mx6 community at the same time.

This might be a dumb question, but that CAI system sounds only like a cone filter with an adapter to the intake and sensor housing. Wouldn't that mean that the filter is still sucking hot air in the engine compartment, defeating the purpose of a CAI???

Yeah, the probesport intake just looks like a pod filter to me, wouldn't you have to add a heatshield and/or run some piping to duct cold air from the front of the car or replace the ducting in the fender to make a "proper" CAI?

Anyway, I fitted a Unifilter Rampod, which is a pod filter, on my '90 626 NA.
It definately makes a difference, fuel consumption went down by about 10%, it sounds alot tougher, and I can feel a small increase in power.

You'd get the same effect from a K&N, even if you just replaced the panel filter in the stock airbox. I think it's the best thing you can get for the money. And you can do it yourself.

I used to have the drop in K&N filter in my GT turbo with a hole cut in the air box which worked well but I just installed a Ractive heat shield cone filter with an adapter that I machined and I'm going to take out the original plumbing in the fender and run a hose off the end of the heat shield down to the bumper so all the filter sees is cool air coming from in front of the car. Right now all I have on is the cone filter and I think it's working well. I've been seeing 9psi boost when I had previously been seeing 8 psi unless it was really cool out. Anyhow, NOPI sells the Ractive heat shield filter for about $30.

No, I took the whole air box assembly and drop in K&N filter out and replaced it with the adapter I made and the Ractive heat shielded cone filter. I've seen links to sites on this site that have the adapters to the MAF for sale so you can install a cone type filter. Just remember that you want to be sucking in cool outside air and not the hot air under the hood.

Right now I have a drop in K&N with a 2 and 1/8 inch shop vac hose running from the bumper all the way up into the box... I noticed a slight difference. Do you think if I got the cylinder shaped filter kit from Probesport (part number AIK-01) I could just put my shop vac hose into the middle of that filter and the car would still suck enough cold air so the engine didn't overheat?

With the probesport model, you will have to use heat shielding. I'm going one step further, and putting on a hood scoop from an '85 300ZX turbo. It will be functional.

Fender

How the m0f0 do you take the fender off. I tried for like an hour and then it was dark out. I got the screws on the top the 2 by the blinker the one on the bottome bumper the one @ the very botom I broke and the one when you open the door @ the top. WTF!!! I need a shop manual!!!
