Thermal intake manifold spacers.

Most are well aware that the reciprocating internal combustion engine is simply a highly modified air pump. While many avenues exist for boosting the power output of an engine, most 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 it's mass flow. If we think back to high school chemistry (or perhaps look forward for some of us) we remember PV=nRT, the perfect gas law. What this means is that, among other things, the volume of a gas increases in direct proportion to the temperature of that gas. In an engine's case, hot air is less dense than cold air and takes up more space. Why is this important to the tweaker? Simple, your engine can ingest more air when it is cooler and denser; more air can be mixed with more fuel, which gives us MORE POWER. An additional benefit for the reciprocating engine is that cooler air has a higher resistance to knock and ping allowing more ignition timing advance or boost in supercharged applications which results in, let's all say it, MORE POWER. This is the theory behind cold air intakes, ice on the manifold, and intercoolers. Thermal Spacers-Manufactured by hand, gasket matched to your specific application.-Reduced waste, most scrap is reused for other projects.-Keeps upper intake cool, incoming air is more dense. -Adds to intake runner and plenum volume.-100% compatible with any mod that uses the stock intake gasket.-Turbo/Supercharger ready.-This equals very inexpensve horsepower and reduced detonation! The Manufacturing Process Starting with the template (a factory gasket), the dimensions are transferred to a piece of G-10 phenolic sheet.The outside edges are cut, holes are drilled and the edges are then sanded to remove sharp corners and loose material.Although Phenolic Resin material cuts like wood, it presents SERIOUS health risks as G-10 is fiberglass encased in resin.A respirator MUST be worn at all times when working with phenolics. Work in a well ventilated area, preferrably outside.Cleanup all dust immediately! I use a 3 micron filter in a 5 gallon "Shop Vac" connected to the tool being used.If you are worried about the health/safety risks or don't want to screw up a $19 per sqft piece of LE (or a $30 per sqft piece of G-10!) material, I'll be happy to make you one! Custom/Special Orders: I can do most with only 1-2 week lead time!

Any tests done that show this actually makes a difference? How much does this mod cool the air?

Several of my friends have done this to their Preludes and S2000's. It is a worthwhile mod as it separates heat producing elements away from the engine, atleast it helps isolate it.
