Ok I live in so cal where it can get to be a little cold during the winter, down to 14 degrees this past winter. I plan on getting my spacer but do I need to get the isothermal package because it does get hot in the desert or do I not need that package?

 

if it gets down to 14 degrees then you want to get the COPPER ISO-thermal upgrade with the spacer. That will prevent your throttle body from freezing up in cold temps.

Thanks!!

 

no need for a tune after the spacer right?

 

no, you would do a tune via utec/dyno time or TS reflash after you have done all your bolt on mods ei: intake, exhaust, hi flow cats, headers, spacer, mrev2. The tune brings all the mods together and helps them work in conjunction, which gives you more power.

Don't bother... If "global warming" is coming you wont need the copper one... lol

 

LOL global warming.... Ok so it will be a little bit before I need a tune then.

 

damn..should have held off on that copper then..lol
