Hey guys I need a little help on my throttle body, my mass air flow sensor, and my Idle air control valve. I want to get a bigger throttle body plus a good high performance air sensor and a decent Idle air control valve. Problem is I have no idea what parts go with each other nor the size of my current ones or any specs. I drive a Monte Carlo SS 2003 model. I also have a K&N air filter (cone) so if there are specific things that increase it's performance that would help as well. I have until the next two weeks to get these parts since I don't want to run my car with ****ty parts and would be incredibly thankful if you guys could help me out on where to get these 3 parts that fit my car and for a good price as well. Thanks in advance!!

 

what are you trying to accomplish with the bigger TB and sensors? more flow? the stock TB will flow fine until you get more mods. for more power, look at ZZP's HV3, ER rockers, Headers, then you would start to maybe need a new TB.

 

I agree with z34phoenix.... A bigger TB is dependent on other supporting mods. Such as ZZP recommends ER Rockers, HV3, and a HV TB. I Sorta cheated and took a cheap route on the HV TB and modded an L67 (SuperCharged) throttle body on mine. The L67 TB has a slightly wider throat for a little more air flow. Here's the info on what I did from my web site:
