so I was recently searching through sites and found this one
P2R - Throttle Body Spacer - 01-03 CL/TL-P - BLACK [P2R-P324B] - $76.00 : High Performance Auto Parts Accessories | Ultra Racing | Unorthodox Racing | P2R

anyone know anything about it....and another thing is, the gains? or if it'll pass smog?
Thanks in advance!

 

Probably won't pass smog. No way p2r cares to pay to get that checked.

Performance gains... nothing noticeable and probably won't see it on a dyno.

I'm reality it just makes the air plenum larger.
I'd put one on for free but I wouldn't spend more than 10 bucks for one.

 

Thanks! good to know lol so not going to invest into that!

 

any air tuning is done in the intake manifold and not before it.
by adding a throttle body spacer, you arent accomplishing anything!

 

the only way to make the air plenum larger would be to add a spacer POST intake manifold.

 

The MDX's (i know i know a six cylinder versus your 4) comes with a manifold spacer stock.

THe TL guys use the MDX manifold spacer to add more torque minus some HP.

I dont know how this will translate to the 4 cylinder, I'm just passing my knowledge of throttle body and intake manifold spacers along.

 

I... uh... hmmm... okay here goes...



If the TBS here is 20mm thick then it has effectively extended the plenum out by 20mm... making it larger. Not larger in diameter but longer, yes.
Regardless the chamber now allows more air which p2r seems to think means your engine is now pulling more air in.
How they put 2 and 2 together and got 5, I have no clue.

Though, regardless where this space is made, it's not doing anything performance wise. You'd get more use out of it on your desk as a paper weight and more torque gains if you took a shit before getting in the car... but hell if I can get one for free (which I'm currently trying to) I'll sport one and add it to the mods list.

This sums it up...

 

^ its a known fact that the larger the volume the intake manifold can hold the more hp it will make with the J series motor(there is a limit though). That is why they made the end covers for the 00-03 intake manifold. Adding that tb spacer though wont do anything as its volume is too small. IF you were to get the thermo gasket spacers, they do however serve a purpose as to help stop heat transfer.

 

you can only add volume by extending runner length. (this is why the MDX comes with an intake manifold spacer and not a throttle body spacer)

not before the throttle body.

 

HOW!? if throttle body controls amount of air?


the throttle body IS the limiting factor or bottle neck.

 

You can also increase the volume in the intake, which is different than making the runners longer for more torque. Its part of what the 2 stage manifold is doing.

Personally i want a large intake manifold with runners that start where the upper and lower come together.

 

.....you mean a 6 cyl vs a 6 cyl...a TL is a 6 cyl lol.

 

would this be more sufficient then?




01-03 CL Type S, 02-03 TL Type S Thermal Intake Manifold Gasket

 

^ IMO just get the Outlaw Engineering kit and call it a day... What you really want is to keep those things cooler and the use of thermal gaskets help a bit with that. (YES EVEN WHEN YOU COUNT HEAT SOAKING THEY DO REMAIN COOLER THAN STOCK).


Is not a very scientific test but before the Gaskets I could not lay my hand on top of the intake manifold after a long run at 60mph in the highway. Now I can comfortably for more than 1 min = thus cooler. I wont say this produces Insta +100HP once installed but at least I can by just feeling it tell, they are doing their job. Keep in mind I also by-passed my TB and VSA TB Coolant Lines since I don't live in a freezing area.

 

Anyone know where we can purchase the outlaw engineering tbs still?

 

^ Seems they gone out of business so My previous Comment is now rendered invalid.

 

Oh I agree! If the tb is no bigger a spacer won't allow more air to go through. I'm just stating that p2r claims.

 

my adversary, usdmJon, has a cute little 4 cylinder.

 

Im a little late here but my TPS is going out in my throttle body. I have a 2002 tl-p with the 3.7 manifold swap and instead of keeping my stock tb, Im looking for one that will give me the best results and not serve as much as a bottleneck. Ive been searching on this topic, but it isn't discussed as much and there doesn't seem to be a lot of options. Thanks in advance.
