what does it do exactly and is it worth doing to my 02 tl non type s

They are spacers made for the IM and throttle body, which also should include thermal gaskets...In other words it helps to dissipate heat that your engine is sucking in, making cooler and therefore denser air...

Is it worth buying? I do not have them, but from what I have heard over my years on here is that it is not a noticeable gain, but I think there is a few hp gain.

look thru the Black Market- Sponsored Sales threads for info on both major brands- the differances and similar theory..

the engine being a V6- sends heat up from its center- right into the intake manifold
A thermoblock spacer for the intake manifold reduces the temp transfer up to the aluminum - which happens to be an excellent conductor of unwanted heat~

another spacer is for the TB to manifold connection, the TB is heated by the engine antifreeze/cooling system- to prevent icing inside the TB!! in certain condition- can occur even at 70 degrees! not fun
the spacer seperates that heat from going to the manifold

Also,, as the incoming air from the filter hits the TB its speed increases and is compressed= creating heated air! again, not what we want

coolest air possible = max air density= best combustion= max torque..that makes the car go forward!

what will you actually feel? a slight move to the left on the torque curve
sea level type power at 5000 feet and 90 degrees
maybe a liitle fuel economy gain that can also be attributed to the egr system cleaning and TB service you should do while its apart for the spacer installation
worth 100 for the one I got? sure!

thanks and it will fit on my tl even though its not type s right??

Type S and TL-P are 2 different spacers I believe. I have the ThermoBlok IM/TB spacer on my TL-P with intake/exhaust. My car still does feel responsive even after a long 20 min drive after I installed these spacers. Maybe it's due to the lower temps on the IM and TB.

dyno proven, but the butt dyno is not proven...not worth it unless you are gonna go all out with the intake and headers and everything.
its a good addition, not stand alone, is what i was getting at...just my opinion though...gl

a lightweight crank pulley and thermospacers will make it a new car,,better than it was!
5hp at the wheel isnt much but the temp control is the big bonus,,

it runs like sea level hp @59f, (standard for measuring) no matter how hot outside or how long the engine has being heat soaked during a trip to the mountains
still runs like it should

Toms02TL, don't get the P2R spacer. The Type-S spacer won't fit your car. Also, P2R only makes a TB spacer for the TL-P (non Type-S). It would be better to get an Outlaw Engineering kit that comes with an IM (intake manifold) spacer AND a TB spacer for roughly the same price.

Or, if you don't want to spend any money, just bypass the coolant in your TB. That will effectively serve the same exact purpose of a TB spacer, if not better. Of course, don't do it if your temperature drops below 60F (just to be safe).

sorry,,, but bypassing the hot water to TB is in no way the same as insulating the entire manifold from the heat rising off the engine

Yes, it is. The entire purpose of spacers are to reduce the temp of the IM.

The purpose of the IM spacer is to keep the engine's heat from rising into the IM. TB bypass will not do anything for that.

However, the purpose of the TB spacer is to keep the HOT throttle body from heating up the IM. If you bypass the TB coolant, the TB will have no heat to transfer into the IM. Therefore, the TB spacer becomes relatively useless.

P2R doesn't make an IM spacer for the TL-P. Outlaw engineering does, and that will obviously do more than just a TB bypass.

^My first suggestion was to get the Outlaw kit that comes with both IM and TB spacer.

I then stated that the TB bypass will serve the same purpose as the P2R TB spacer. I didn't mean to imply that the TB bypass would stop the heat from the engine to the IM. Obviously, that wouldn't make sense.

they way you phrased it was confusing to this old frail mind~

type P outlaw only

Type S P2R or outlaw has one for you

huge amounts of heat come up from the center of our V6 engine,,right into the bottem of the intake manifold
If you can reduce that by any amount it will help the car
