If you don't know already, the cooler your intake air is the more HP your car will achieve. We present you the answer to this age old problem, raising the intake manifold off the engine with GrimmSpeed's new real Phenolic Intake Manifold\/TGV to Engine Thermal Spacer.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003ePhenolic spacers have been used for years by many other specialized automotive companies, but this is very new technology to the Subaru world.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhat it does:\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e* Greatly reduces the transer of heat from engine to intake manifold thus reducing heat soak.\u003cbr data-mce-fragment=\"1\"\u003e* One of a kind true Phenolic material, not cutting board material like others.\u003cbr data-mce-fragment=\"1\"\u003e* The cooler your intake temperature is the denser the air is which leads to more power * For every 5 degree reduction in temperature, increases power by 1%.\u003cbr data-mce-fragment=\"1\"\u003e* The cooler and denser the intake air that the engine sucks in, increases the amount of air that can be mixed with fuel thus increasing efficiency.\u003cbr data-mce-fragment=\"1\"\u003e* Direct bolt-on.\u003cbr data-mce-fragment=\"1\"\u003e* When running the oem gasket only, your intake manifold gets very hot to the touch, enough to burn your hand. When the oem gasket is replaced with our Phenolic Spacer, your hand can be placed on the intake manifold without any issues.\u003cbr data-mce-fragment=\"1\"\u003e* We have installed both with and without OEM Subaru Gaskets and have had no issues with either way. We do recommend using 2 sets of oem gaskets however, one on both sides of the spacer.\u003cbr data-mce-fragment=\"1\"\u003e* USA made\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eHow it works:\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e* The intake air in your engine travels through the airbox into the turbo, then into the aluminum intake manifold. The air exits the intake manifold and goes directly into the engine.\u003cbr data-mce-fragment=\"1\"\u003e* While the intake air is within the intake manifold it picks up alot of heat from the aluminum intake manifold. This added heat reduces air density thus reducing engine power capabilities.\u003cbr data-mce-fragment=\"1\"\u003e* In stock form your engine has a steel gasket between the intake manifold and engine which allows the heat from the engine to quickly transfer into the intake manifold. By replacing this steel gasket with the GrimmSpeed Phenolic Spacer you are greatly reducing the transfer of engine heat into the intake manifold.\u003cbr data-mce-fragment=\"1\"\u003e* Phenolic Spacers are able to withstand 500+ degrees F. Subaru engines run at around 200 degrees F, so the Phenolic Spacer is well within its max running temperature. GrimmSpeed has tested that it is also safe to run race fuel, E85, and methanol with the Phenolic Spacers.\u003cbr data-mce-fragment=\"1\"\u003e* The Phenolic Spacer will conduct 300-900 times less heat than the oem steel gasket.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003ePACKAGE CONTENTS\u003cbr data-mce-fragment=\"1\"\u003e1 Pair Thermal Phenolic Spacers\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eBelow is an exerpt from a 3rd party's study(non-Subaru)...\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\"Why it Works\"\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhile many avenues exist for boosting the power output of an engine, most approaches focus on ways to increase the volumetric efficiency of the system. Ported heads, larger diameter exhausts, headers, and bigger throttle bodies serve to decrease the resistance to airflow through the engine. The modification shown here, however, does not increase the volume of air flowing through an engine, but rather increases its mass flow.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eCold air is more dense than hot air and takes up less space. So if your engine can ingest cooler air, more air can be mixed with more fuel, which gives more power. An additional benefit is that cooler air has a higher resistance to knock, allowing more ignition timing advance - or boost in supercharged applications. Either way, they both equal more power! This is the theory behind cold air intakes, ice on the manifold, and intercoolers.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe intake air in EFI engines is drawn through the airflow meter and throttle body, and then into an alloy intake manifold. During its residence in the intake manifold casting, the air charge picks up unwanted heat from the manifold, increasing its volume and lowering the resistance of the engine to knock.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eOne of the possibilities for reducing the intake air temperature is to install a cold air intake. However, another possibility is to reduce the heat conduction from the hot engine to the intake manifold by thermally separating the two. By replacing the steel intake manifold gaskets with an insulating spacer, heat conduction to the manifold can be greatly reduced. The best material for the spacers has a low thermal conductivity, high compressive strength, is able to withstand up to 300 degrees F (~150 degrees C), and is affordable. Phenolics, with excellent insulating properties, high stiffness, and the ability to withstand 500+ degrees F (260 degrees C), are commonly chosen for similar applications. Additionally, the coefficient of thermal expansion of a phenolic is similar to that of aluminium, which helps to reduce sealing problems in this particular use.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhen compared to the 0.025 inch steel gasket it replaces, a quarter inch thick phenolic insulator will conduct 200-1000 times less heat! Although the insulation benefits increase with thickness, ¼ inch (6.4mm) sheet was chosen because this is the thickest that can generally be used with stock mounting studs and bolts.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eManifold Temperature Data\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe basic function of the insulators is to reduce intake manifold temperatures, so what better way to test than to record and compare temp data before and after the install? I took the temperature readings from the front centre intake runner using a professional quality CPS T200 temperature sensor with a time constant of the order of 5 seconds. The sensor was mounted on the front middle intake runner for all tests and the vehicle was driven as close to 60 mph (~100 km\/h) as traffic would allow. After the driving test, the engine was allowed to idle for a sufficient time to show the maximum temperature.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe data is shown as a temperature change above ambient. As you can see, the temperature of the intake manifold reached a steady state of approximately 30 degrees F (17 degrees C) lower - 40 degrees F versus 70 degrees F - with the insulators than without during 60 mph cruising. During the idle test (the higher temps at the right end of the graph), the non-insulated engine was 52 degrees F (29 degrees C) hotter and still climbing when the test was aborted. A non-quantitative comment: I can place my hand on the intake after a drive with the insulators installed, whereas I would have burned myself previously!\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e…. Summary\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eHaving seen many people shell out hundreds of dollars for performance mods of dubious value, I wanted as much data as possible to show that this intake manifold insulator thing really worked. I was able to show that:\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe intake ran 30 degrees F (17 degrees C) cooler at cruise and at least 50 degrees F (28 degrees C) cooler at idle; According to my dyno plots, I gained up to 7 horsepower and 11 ft-lbs of torque over the major portion of the power curve.
