throttle body spacer.

i have the 4.0 v6 does anyone have a throttle body spacer.
is does it make any difference?
i also have a k&n cold air intake if that makes any difference.

 

hahaha remember my first write up here?
to be honest I took min off. For our application it runs better without it.

 

so not worth the money?

 

I don't think anyone has done a dyno on it. You can be the first then you can tell us if its worth it or not. Otherwise, everything else are just opinions.

 

I've got one. Not worth it. Don't waste your money.

 

Let me re phrase that, I have not seen a dyno on a 1GRF yet. It is old school design that probably worked best with carburators but yet coming from a different forum, I have seen dyno's on a EFI K20 engine that resulted on a 2-3 hp/tq gain at the wheels. 2 different spacers, multiple dyno runs, same results. I personally don't have a spacer in my truck since it seems that the 1GRF doesn't seem to respond much to CAI (trd) which has minimal gains compared to the K20 which resulted in about a 10-12hp gain. All I'm saying is that I have not seen anything that proves it works or disproves it doesn't with the 4.0.

 

Either one of those will make a difference ... on your back pocket. They will definitely lighten the load!

 

I'd be the first one to pay the $75 for it if I get a 3hp/tq gain. That's $25 per hp/tq. That's a lot less $$ than a CAI that gives 5hp for at least $250. I guess Toyota's MAF doesn't respond too well with a cai.

Although an improvement here and there adds up in the end. (no stacking hp's) URD Maf cal makes CAI's more usable.

 

Yeah but you don't get that with a TB. Instead you get a mean whistle! haha I took mine off, it didn't help with anything.

 

Wow! The guy who got me to buy the TB swore up and down that he got an increase in power and mpg on his 3.4. Glad I didn't buy that...
