First off, do trottle body spacers actually do anything to help the car(horsepower, torque, MPG, sound)

Second are they actually worth the $100 bucks or around there

Third, if I do buy one which is the best to buy for my 2010 TL? What brand will give me the biggest improvements?

Please let me know if I should buy one or not

I do a K&N intake installed as well

Thanks guys!!

 

Personally I'm almost certain it's pointless, if you are really looking for tiny things to do like that then you could do the coolant delete trick for the throttle body that some of the guys on here have done, and that's practically free. Don't waste your money on stupid things like that. Save up for a j pipe or something that might actually get you some return

 

j-pipe and PCD to me are the only parts worth modifying.. maybe an intake and exhaust to free up the air flow but thats really about it..

 

any air tuning is done in the intake manifold and NOT before it.

adding a throttle body spacer is not worth 1 dollar.


and you guise should look at better cold air intakes than the "branded" ones.
those are puny intakes.

if going for power, use a 4 inch diameter pipe all they way.
dont use a tapered pipe like AEM, injen, etc.
