I'm doing a top end rebuild on my car. The air injection lines are sure ugly and clustering up a lot of space. I live in indiana where legality isn't necessarily an issue, but it could be in the next 10 years. I'm wondering how much that air pump actually helps emmissions and if it's worth keeping. it'd sure clear up some space without, but i hate to go through the hassel of putting all this back on in 5 years to be legal. i don't think we'll ever get much farther than mandatory yearly sniffer tests, but who knows. I'm going to be buying jethots and i have to choose between lt's with or without air hookups. need some advice...

if your going to be putting in LT's, i really dont see the need to keep the smog pump to try and pass an emissions test some day. you wont pass emissions with long tubes even with the pump. i do believe that you can put on shorties, keep the pump and you will pass emissions. someone else will have to verify this info for sure.

 

its to help heat up the cats during start up. after that, it doesnt do anything else.

 

shorties will pass. my car did. why wont lt's pass?? it seems the same aslong as u put o0n a cat

 

If you diable the AIR you'lll have to have the code edited out so you won't throw an SES light, however your AIR monitor will stay not ready.
Here in buffalo we're allowed 2 not readys to pass an OBDII scan for emissions.
You'll need 3 out of 5 monitors to pass.

 

94 odb1's are not too sensitive to smog and air. usually, u can unhook them and the computer wont do a thing.... but since i'm doing a cam swap, custom tuning will be apparent anyway

 

LT's can fail the visual inspection as the cat(s) are not allowed to be relocated from their stock position. The further back the cats are located, the colder the exhaust gas and then the cats don't work as well (they rely on heat to function).

 

technically, you're not even allowed to touch the cats before 75,000 miles (or close) unless there is a problem with them...if you want to be strict. In states like mine, we probably wont see much more than sniffers. there are no mandatory visual inspections in the midwest as far as i know.?
