Ok. There's been talk on this forum about "performance" intake manifold gaskets. What it's
theoretically supposed to do is cool the air going into the cylinders. Here's the theory behind it:
1) Cold Air enters the Cold Air Intake
2) Cold Air travels from filter to plastic Intake Plenum
3) Cold Air travels from plastic Intake Plenum to ceramic Intake Manifold.
4) Cold Air travels from ceramic Intake Manifold past a metal gasket to the aluminum Cylinder Head.
5) Combustion happens and creates heat
6) Heat created from combustion travels from the Cylinder Head through the metal gasket and to the Intake Manifold
7) Heats up the incoming air from the ceramic Intake Manifold and the cold air intake is no longer cold.
Now, as I'm sure you've all noticed, the car performs better in the morning. The reason is that cold air is denser than warm air, therefore, you can fit more air into the cylinders. More air = more fuel = Bigger Boom!
Just so you know, you gain 1.5 HP at the crank for every 10 degrees Celsius of cooler air compared to engine temperature.
This product is to prevent/slow down the transfer for heat from the Cylinder Head to the Intake Manifold and therefore, you get more horsepower.
Here's the product itself (sorry, it's upside down):
All it is is a piece of plastic that's about 1/8" an inch thick.
I'm not here to say if they work or not. I'm here ONLY to do a DIY on the install. So as per usual:
Fitfreak.net and/or "Fit of RAGE" is NOT responsible for any damages, warranty-void problems. DO AT YOUR OWN RISK!
Tools needed:
10mm socket
12mm socket
4 inch extension (roughly)
ratchet
Flathead socket
needle-nose pliers
***WHEN REMOVING BOLTS, COUNT "DOWN" (6, 5, 4, 3, 2, 1). WHEN INSTALLING BOLTS, COUNT "UP" (1, 2, 3, 4, 5, 6).***
Good Luck!!
First off, here's an exploded diagram so that you can see what you're up against:
1) take your dipstick out:
2) Take the engine cover off. There are 2 x 10mm and 2 x speed clips:
3) Remove the 5 x 12mm bolts that hold the Intake Plenum to the Intake Manifold. REMOVE IN A SEQUENCE PROVIDED & REMOVE THEM IN EQUAL ROTATIONS!! (this prevents warping)
4) remove 2 x 10mm and the vacuum line:
5) Remove the 6 x 10mm bolts that hold the EGR plenum to the Intake Manifold. Again, REMOVE IN A SEQUENCE PROVIDED & REMOVE THEM IN EQUAL ROTATIONS!!
6) Remove the 5 x 12mm bolts that hold the Intake Manifold to the Cylinder Head. Again, REMOVE IN A SEQUENCE PROVIDED & REMOVE THEM IN EQUAL ROTATIONS!! Some bolts are hidden!
7) CARFULLY remove the Intake Manifold and here's what you get:
8) install the P2R plastic Intake Manifold gasket/spacer
9) Now, put everything back in reverse order. When it comes to tightening bolts, TIGHTEN IN EQUAL ROTATIONS AND IN A CLOCKWISE ROTATION AND/OR IN THE SEQUENCE PROVIDED IN THE PREVIOUS STEPS. Keep in mind that you are tightening into ALUMINUM (Cylinder Head) so DO NOT STRIP THE CYLINDER HEAD!!
Sorry, I forgot to take pics of it installed. I got too carried away and needed to go so I threw everything back together without pics. SORRY!!
Hope everything works out. Hopefully you'll notice a difference. Please feel free to ask any questions!
