If I whould put a open air filter on my 91 RS TBI 305 instead of the stock one whould I have to worry about not using the hoses and wires hooked up to the old air filter
Thanks

 

All you would need to do is prolly plug that vacuum line and put a breather on the Crankcase filter tube(inplace of the tube). Should work well.

and dont forget to remove the temp sensor from the bottom of the stock air cleaner and keep it pluged up(your ses light will come on if you leave it unpluged). just move it off to the side out of the way. but keep it away from the exhaust.

 

Ya, my 86 doesnt have the temp sensor, forgot about that one!

Block the vacume line at the TB, drill a hole in the new air cleaner bottom and install the IAT module there.

 

Great? this is exactly my problem. I just Added a Goodmark Cowl Induction hood, and added a high flow aftermarket air cleaner but did not have anywhere to put the IAT sensor so I didn't plug it back in, and my Check Enging Light started coming on.

Anyone know of after market 14 inch Air cleaner that has a hole for this already? or should I just buy the appropriate size drill bit to make my own hole for the sensor?

 

Just plug the IAT sensor back up and tie it off to the side some where with a zip tie(not near the exhaust manafold) or tuck it under the air cleaner near the dis and coil.

 

wouldn't leaving it out of the air cleaner cause some things to change in the ECM? like timing adjustments or something? ive been reading on these boards about people movind there IAT sensor around. and getting differnet results..

 

The IAT is just what it's called....it senses the temperature of the air at the inlet. People move them around on TPI setups to help offset the heat saturation that can be caused by the aluminum intake, with a TBI system that isn't a problem. The air near your air cleaner is the same temperature as the air being pulled into the air cleaner, so as long as it isn't next to the exhaust (lots of heat there) it will work just fine. The extra heat from the engine bay will just make your car think you're in Pheonix.
