Here's a pic that 07_HFP_Si took of the job we did when we installed his IMG TBS and a stainless flexible upper hose (to eliminate the interference between the CAI elbow and the coolant hose).



I pulled his picture from:

Cool Flex, Anyone checked these out?

I recently installed my spacer and feel that it really compliments my Fujita SRI. The car pulls harder at all revs and throttle response is way better than with just the SRI. I recommend it for the price.

did u notcie a loss of sound from intake or diffrent sound i guess

mine is loud. I have a injen sri though

I need an engineer's opinion. I've seen pics in this forum were some users installed a throttle body gasket, spacer, and gasket prior to their intake. i'm curious as to the function of the second gasket. its already thermally isolated from the throttle body via the first gasket. is this needed/recommended because i may run into some interference with my injen cai plumbing. Thanks.

You're right, there isn't a real need for the second thermal gasket except for the fact that you cannot reuse the OEM paper gasket that currently sits between your throttle body and the intake manifold. You could source a second paper gasket from Honda or elsewhere but I'm going to guess it would be about the same cost as the second thermal gasket (some vendors have a package deal that gives you a break if you buy two at once). Also, the gasket, being about .100" thick, is probably part of the increase in intake manifold volume that yeilds the performance gains. Another point is that the bolts that come with the spacer are the right length to work with both gaskets installed. While the bolts probably aren't too long to work with only one gasket, I didn't go through the trouble to ensure that they weren't too long.

One last point, you will have tons of interference with the CAI "elbow" regardless. So much interference that one .100" gasket won't change it much. What you need to do is buy a different upper coolant hose (rubber/stainless or whatever your pleasure) that routes away from the CAI elbow and then you've got the proper solution to the problem. See other threads on what options are available. I helped a buddy of mine (another member here) install a stainless hose to fix this so I know that solution works from experience.

Thanks for your quick response. The SS hose should not be a problem but i can refer back to using a longer rubber hose due to the costs. i dont think it'll be an issue. As long as the supporting brackets and intake filter in the bumper remain where it sits, i'll be more comfortable. also, i'll double check if there's enough thread engagement for the bolt into the spacer and gaskets. 1 more stupid question: Does the new bolts come with the purchase of the spacer?

except the oem gasket IS re-usable

I've done a few of these and even on my car, which was about two months old and had less than 2000 miles on it, the gasket sticks in one or two spots and pulls small bits of the paper apart. Even if you were blessed with a paper gasket that hadn't stuck in any way, shape, or form its not common practice to reuse paper gaskets especially when the profile of what you're going to compress it with on one side is different from what was previously installed. If you were saving a substantial amount of money it might be worth considering trying but come one, it's like $11-$15 extra dollars! WAY below my threshold of having to worry about the integrity of a post MAF/throttle plate seal that's subject to almost 15 PSI of vacuum.

Yes they do though some folks report some surface rust on theirs over time so if you're concerned about show quality results in the future you might want to locate some stainless bolts.

guess i'm lucky then, because mine came off flawless and i have zero problems since the install

which was a year ago, but thanks for the info

I installed my red spacer this morning. As a newbe I thought I would try installing something myself. It took me about 90 minutes. Nothing too tuff, removing the two studs were probably the most diffucult, but read all the previous posts and its a piece of cake.

Definately worth the $. The car definately performs better with the spacer than with out. I have an Injen short induction and it sits directly on top of the radiator hose. I need a flexable hose to redirect the hose. Definately worth the money. I love it.

NAPA part# 7777......ask me how I know. lol cut a 1/2 inch off of each end and it fits perfectly!! Did my TBS and gaskets install this morning, thought I'd swap out that hose while I was in there ( was rubbing on the underside of my AEM short-ram intake. Everything fits like a glove now!

[michinsi]

Anyone have the TBS with an AEM sri?

Can you post some detailed pixs?

[Evasive]

I Just recently installed my throttle body spacer :

from p2r...Funny thing is (unless i missed something) it came with the 1/8 plastic port piece but my spacer didnt not have a hole in it for it.. on the back it just says SC TUNED encrypted in it...I checked all the sides of it and no plug hole for the plastic piece to be screwed in!!!.Did i miss something here?

[ccking85]

hmm. Mine came with the hole in the spacer.

[Evasive]

anyone else??? i reallly dont think i overlooked it,,,,,,
