Intercoolers And Piping Kits

Intercooler Upgrade Kits

An Intercooler works to increase horsepower not by increasing boost, but by lowering the temperature of the intake air. The colder the air is, the more densely packed its molecules are. Therefore, more air can fit in the same combustion chamber volume. Additionally, by lowering the temperature of combustion gasses, engine wear is reduced and longevity increased.

The stock intercooler is designed to make the engine run safely at the factory set boost level. The intercooler upgrade kit replaces this stock intercooler and reduces the temperature to well below that safety margin. The upgrade kit alone makes a very noticeable horsepower increase, while its increased safety margin allows for further modification of boost pressures.

All kits are supplied with all necessary hardware for installation. The piping supplied is considerably more rigid than stock, which prevents the piping from collapsing during hard acceleration. The HKS kits for 86-92 require extensive notching of the radiator core support to clear the new piping, since the new intercooler is mounting in front of the radiator. The GReddy kits for 86-92 require minor re-aligning of the turbine.

Turbo Piping Kits for 93-95 The factory rubber piping tends to expand and contract, as well as blow off periodically. Aluminum piping kits are stronger than the factory rubber kits, and add a nice touch to any engine bay.
	These GReddy kits have two cast aluminum pieces, and one thin wall mandrel bent tube, all highly polished. Supplied with all needed connector hoses and clamps.	12040900
