We offer a large selection of aftermarket High Performance engine parts and engine kits. These parts provide superior performance advantages and engine longevity.

PAI’s High Performance Piston Skirts are treated with a new and highly developed anti-friction coating process. The coating is designed to lower scuffing and wear while providing a dry lubrication that is highly resistant to contamination and reduces parasitic drag. HP-3 is a proprietary formulation of anti-friction coating applied to the piston skirt to decrease friction on the cylinder walls.

As the largest friction area, the cylinder wall represents the largest loss of power and efficiency anywhere in the engine. HP-3 coating drastically reduces friction and allows for tighter clearances between the piston and cylinder wall. This reduction in friction and clearance improves overall performance, lowers oil usage, and oil temperature. This increases the life of the skirt and ultimately the life of your engine.

HP-2 Ceramic Thermal Barrier Coatings are applied to piston domes by a proprietary process that literally co-mingles the coating material with the substrate for a super high strength bond.  

HP-2 provides a more effective, even fuel burn throughout the combustion chamber while maintaining a higher nominal temperature. This high temperature build-up is turned into usable energy. This surplus of energy is then converted into horsepower, rather than dissipated through the pistons. This process is proven effective with all engine types, including turbocharged engines.

This thin, smooth ceramic coating insulates the piston so oil contacting the underside will not absorb a high amount of heat. This in turn helps reduce oil temperature.

At the heart of PAI’s High Performance Bearings, is the new F780 Material which provides 15 times higher load capacity, a longer life and an improved fatigue resistance over any other standard bearing material. The latest addition of the HP-1 coating lowers friction to 1/3 of the original value, thus preventing abrasive wear. Despite there being several systems in place today to prevent engines from experiencing low or no oil pressure, these conditions still do exist. The extreme weight of a crankshaft resting on a non-lubricated bearing can have devastating effects on the life of the bearings. PAI's High Performance Bearings provide a source of much needed lubrication in such conditions.

Parasitic loss due to friction robs the engine of power, creates higher temperatures and excessive wear on the drivetrain. PAI’s High Performance piston pins have been specially treated with an Isotropic Superfinish to combat parasitic loss.

The resulting low friction surface allows the drivetrain to run smother, freeing up power and improving fuel economy.

Power loss due to sliding contact between parts, micro-welding and liner galling are all problems created by excessive friction. Built to survive in highly demanding, performance engine; PAI’s High Performance ring sets increase the engines performance and durability. The HP-1 coating provides a solid lubrication to the contact faces resulting in higher load carrying capacity and friction reduction.

When the engine is running; the microscopic peaks of the surface of the piston ring groove and the piston ring rub against each other, Micro-welding occurs when the combination of the cylinder temperature and the friction created from these peaks rubbing together is enough to momentarily melt the peaks. When the peaks melt they bond together, but because the area is so small: the bonds are weak and quickly broken, The result is part of the metal from the piston ring groove or the piston ring is transferred to the other surface.

To meet more stringent emission standards and fuel economy, todays modern engines are continually being challenged to increase pressure and temperature conditions in the combustion chamber. Even older engines that were previously designed for 400 horsepower output are now being modified to run at 600+ horsepower. The increase in combustion pressure can cause numerous problems such as liner scuffing, flange breaking, increased blow-by, high oil consumption and high heat transfer.

PAI’s patented cooling design provides stability of the liner. Combined with high alloy gray iron material to increase tensile strength, the PAI liner can handle the extra load that new engines demand. 

The patented radial grooves in PAI’s cylinder liners increase the surface contact area between the liner and the coolant. The result is greater thermal transfer rate and a cooler liner. Combined with stronger materials and improved manufacturing techniques, the PAI liner shows greater durability than the OEM liner.

All our High Performance engine parts and engine kits carry a 3 year parts warranty.
