    Cold Air Intake Upgrade with HO mods

    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.

    Just my

      You're drawing much warmer air in with that intake than the stock one.

        The factory intake was too flat and had too many bends for me. The "new intake" will be better.

            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.

                  Custom87, What happened when you got your dyno results?
