did the 91 and 92 z28 350 tpi come with a massflow air sensor ?

 

90-92 tpi is speed density and uses a map sensor.

 

so just the tpi boot hooks up the air duct

 

on camaro's the throttle body bellows to the air filter assembly, fire birds have a duct and the air filter in the rh fender well. On speed density tpi you can install a air filter on to the throttlebody but drawing in colder dense air is better.

 

so on a 92 z28 what type of filter goes on the tpi boot ???

 

you could use a k&n rc5000 or rc5050 on the throttle body.
