What size plug for 94-95 stlye headers to plug the AIR fittings?
Also 96-96 stock manafolds? same size as 96-97 style air fittings for headers? I know they are different from the 94-95 style... all help is appericated... Im trying to get all my parts together for the install, im just waiting on some misc parts, gaskets/bolts, plugs n wires. y-pipe and high flow cat are in the mail... anyways please help. THANKS TO ALL!!!

 

SAE 7/8-18 inverted flair i had to have mine made any nuts and bolts/hardware shop can do this somepeople use m22 but mine fit exactly without tearing up the threads.

 

I used the M22 oil drain plugs on my 94 and they fit the threads better than the stock fittings.... definitely did not "tear up the threads". You can get the M22 drain plugs for about $2.50 each at a well stocked auto parts store. Get a couple of copper washers while you're there.

 

Thanks guys! Are the 96-97 a different size??
