Having just installed a AEM cai, I was woundering about how the coolant running through the TB has a effect on how well the cai works, like does the coolant in the TB basically render the cai useless, or at least less useful? I'm aware of the TB bypass, but I live in New Hampshire, where it can be freezing in the AM and in the 70s or 80s during the day, so I'm not seeing that as an option. Any thoughts?

 

I wouldn't worry too much about the TB bypass. The coolant heats up the throttle body a little bit which in turn may heat the incoming air some. I think I read somewhere that it was worth 1-2hp. Nothing to get too concerned about if you live in a cold climate and you need the defrosting effect. If you really think that you need that extra pony or two you could go ahead and bypass it and see if you have any problems. It only takes like 15 minutes.

 

yup it isn't that bad to do and should get a few ponies from it but nothing you will fell. m02

 

I wasn't looking to gain anymore power- I was curious if the coolant would heat the TB to the point it cancelled out the benefits/gain of a cai

 

Well Unfortunantley... The CAI is only good for like 5hp..

Some people will argue, but its more of a Complimentary Mod...

 

I have run several cars in the winter with a TB bypass with no ill effects. Nor do you see a big difference cold air or not.

Also being from NH, I would say don't do it. I believe it is there to stop the TB blade from getting frozed open or shut, either way it dosent hurt.
Remember two winters ago when it was -20 for a month, it was too cold to snow!!

I would see it as not being worth it in this Climate. Unless you want to have it off in the summer and put it back on in the winter? I personally would not do it, but thats my opinion.

Good luck either way

 

I'll say it again- I never had any plans to bypass the TB! I was just woundering if having the TB being heated would cancel out the effect of the CAI drawing in cooler air. Either way, its been a week and the cai definitely has helped in the mid to upper RPM range
