I don't think anyone has ever deleted those systems, so there couldn't possibly be any search results on the topic.






I'd suggest searching in the Gen III External section.

I just don't understand why people remove AC in street cars.

Want to go fast? Make more power.

Well I live where I don't need to pass smog so anything that has to do with Exhaust gas recycling (EGR system) or smog I don't need in my car. I also don't use my AC at all not that it works. so its just added weight.T-tops and windows are good enough... Hottest it gets is 110 rarely.

Block off plates for EGR and a tune. You can remove the AIR pump as well....again, block off plates and a tune. A/C? You are crazy ...jokingly of course. Anything above 80 degrees is A/C weather to me.

When you take off your EGR and associated items let me know I want it.

Alright I'll keep them for you... I'm dead serious about my A/C... it hardly works and I don't use it anyways... just roll down the windows and take of the ttops.

AC Air and EGR are easy.

AC just unbolt it, remove the belt, and pull the lines, the compressor and the condenser. If you want to clean the bay up a little more, cut the plastic box out and remove the inner heat exchanger for the AC and put the HVAC delete plate over it and cut holes for the heater lines. (What I did. Just made my own plate.)

Done. I pulled mine because I have a convertible and I drive with the top down whenever I can.

Air system. Under the fuse boxes is the pump. Unbolt the lines from the exhaust manifolds, make or buy block off plates for them. Take the lines out and pull the Air pump. Done.

EGR unplug it and unbolt it. Plug the EGR port on the intake. Done.

For removing Air and EGR you will throw a code. You can turn off the codes with a tune. You can do it yourself if you have the program or just ask your tuner to do so.

If you want to pretty up the engine you can relocate your coils to where the AC compressor was. That's where I mounted mine. Just built a bracket and bolted em up. Needed extension harnesses and new wires but very worth it.
