I plan on swapping to the HO upper intake along with the HO TB that I have from a 90 mustang GT along with maybe fabricating a CAI. The stock airbox doesn't seem like its that restrictive, but I have noticed an improvement on other cars. My truck had much more restrictive intakes though, I had to cut part of the sheetmetal next to the radiator since the original intake only had a pin hole to suck air through.

This is what I'm running right now. I didn't do any "Before" and After" dyno tests to see if I was making any more power over the stock numbers. The flat, "ribbed for her pleasure" factory air intake looked like one of the "Lost in Space" robot's arms to me.

I used parts from the MAC cold air induction kit. If this inlet tube was extended about 12" and the air filter enclosed, I think it would yield a little more power if it made any difference.

You're drawing much warmer air in with that intake than the stock one.Originally posted by N AThis is what I'm running right now.

I have installed the HO upper/65mm TB and Bored EGR Spacer,with a custom CAI I fab'ed myself on my stock motor.With the CAI,I deleted my washer fluid/raidiator overflow tank,and cut a hole in the fenderwell which the CAI pipe runs down into and the filter attaches on the other side,making it a true cold air intake which is much less restrictive than the stocker.I also made a splash shield for the filter to protect it better during rainy days.I'm not gonna get into the dyno results because of what happened last time when I did,I'll just say It did make a difference.The HO upper,and 65mm TB and EGR Spacer will also give you a nice gain in throttle responce,the stock lo-po's are quite pitiful and should have never been put on our 302's.Good Luck!

Any improvements in potential air flow with a true CAI will be magnified if you eventially do a head, cam, header, gear, etc... swap. The pitiful factory motor doesn't need all that much airflow potential unless you bolt on a N2O plate.Originally posted by 87mefullI plan on swapping to the HO upper intake along with the HO TB that I have from a 90 mustang GT along with maybe fabricating a CAI.

The "new intake" will be better.
