Well am looking into all except jet for throttle body spacers and every one is saying the cfm throttle body spacers are tthe way to go with increase.I might do that one or arid not sure yet and also a injector spacer,has anyone used the injector spacer with a throttle body spacer together and would it be worth it ?

Mine is from Jegs. I think its the cheapest out there. I would stay away from any of them that look like the airaid one. I'm not a beleiver in it. My plan is to eventually take my spacer off and make it tapered.

yea u could make one,wouldnt be to hard
the open one would be ideal if u could find one

i just just orderd a injector spacer on ebay for $12.98 why not for that price. i also found out why thay say its not for the 454 its beacuse the factory 454 tbi already comes with it!!! so it must do some good if GM makes it.

Well i was think the injector spacer and the cfm spacer becuase i read alot last night and everyone was pleased and made great gains in power and mpgs like 1.5 sold not bad.But redchevy has a good point if the 454 throttle body already comes with a injector spacer the it must do some good.
