Where can i find a good air intake for an 85 tpi 305? Will i notice a large perfoemance increase? Will the air intake get rid of the MAF sensor?

 

You can get them many many places. Like summit or jegs. No it will not give you a large power increase and no it will no take away your MAF sensor.

 

I made my own. I wasn't going to pay the 200 something for an intake that isn't hard to make for way less. I paid about $46 for mine. Just used plumbing supplies, exhaust tubing, and the stock MAF (you have to use this or you get MAF codes, the check engine light comes on, plus the engine uses this to determine how much fuel to mix with the air) It took about 2 hours to do and I did it using just a flat head screwdriver, socket wrench, and scissors. The car performed A LOT better with the new intake. If I was you I would try to do it yourself and if it doesn't work out you can just go get a kit.

 

Make your own. Mine cost me about $100 WITH the dual K&N 4" filters.

I dont see a MAF sensor on that CAI

 

Because it is Speed Density. Which uses a MAP.

 

John how did you mount you KnN's?
got pics?

 

Yes, I posted the link up top to the pictures of the K&N's. They aren't really mounted, just tied into position.

yeah, that plastic tubing wouldn't that create alot of resistance with air flow. I would think you would want a more smoother inner surface, especialy with curvy tubing.

 

With tubing that large, even the stock single tube, the diameter
is large enough to flow way more air than the motor can use.

 

Make your own. Tons of post on this. Instructions on my website on how I built mine. NO...it won't eliminate your MAF sensor and if you don't keep the MAF you will get a 34 code and screw then ECM up.

 

hey buddy, did you use the maf elbow or cut it and use another elbow. I got almost the exact same setup. And on the rubber elbow with the 90 degree turn connected to the factory rubber connection from the trottly body, does the rubber fit nug enough on yours or do you have pvc hidden under it.

 

That is the MAF 45* elbow....works great with a little silicone sealer and a hose clamp. The 90* rubber elbow into the stock throttle body connector is a little tricky. I cut a notch in the elbow to get it into the stock piece then I trimmed it all real nice and used silicone gasket sealer to make it all airtight. Just play with it and be creative. It's all good!!

 

yeah, I just thought of that after I send that message, now that I know it wil work I'll try it. How does that gasket seealer work, is it like a glue or what.

 

Blue RTV is pretty sticky and will act like a glue. Black RTV is more like a weatherstripping composition and will peel away if pulled on. Either one will work. If it is out of sight use the blue RTV. Black if it is going to be seen. Good Luck!!
