Integrated Engineering 2.5L 5CYL Spring/Retainer Kits
Integrated Engineering spring kits for 2.5L 5CYL engines are performance tested kits featuring aircraft grade titanium in-house CNC'd retainers to exacting tolerances and surface finish requirements. Optimized to match your vehicle specifications and provide proper valve control under high revving applications, the springs are wound in the USA from the purest spring steel available in the world and nan-peened for incredible fatigue resistance. These are engineered for the wildest setups, and tested to perform with long life and reliability.
Sold as a complete set of high performance valve springs and titanium retainersOrder here
Ferrea Valve Spring and Retainer Kit
Heavy duty valve springs will prevent valve float at higher rpm. Titanium retainers will help keep the weight down, while providing extra strength. Valve springs and retainers are a MUST for high revving engines!
Sold as a complete set of high performance valve springs, and titanium retainers. Order here
Integrated Engineering Valve Guides
It is always a great idea to replace your valve guides when doing a cylinder head build. These valve guides are made in house on our CNC lathe, using a proprietary bronze alloy. This alloy allows for 10% faster heat transfer, as well as better wear characteristics to make for a longer life. We have designed these with an aerodynamic tip design to cut down on airflow restrictions in the port. These valve guides are made with ultra high concentricity for exact valve placement, with precisely sized outer diameters. Standard 2.5L 20V I5 Sized. Sold individually (20 required for MK5 2.5L 5 cylinder engines) Order here
Integrated Engineering 1.8T Valve Seats
Integrated Engineering valve seats are the performance option for replacing factory seats when doing your cylinder head build. In high revving performance head builds, factory seats are prone to excessive wear resulting in premature valve failures. To combat these issues our valve seats are made from a specialized alloy on our in house CNC lathe for dimensional accuracy. Using a proprietary bronze alloy results in faster heat dissipation where thermal conductivity is increased by 10% and extends valve life, seat erosion, and cylinder head component life.

Integrated Engineering EKagrip 6 Bolt Flywheel Friction Disk
Originally designed for low horsepower, the 6 bolt flywheel interface struggles when subjected to serious power, this interface can become taxed and allow the flywheel to slip around under high torque. This leads to wear between the surfaces, and shortly thereafter complete failure of the bolts and joint. This ruins the flywheel and crankshaft, and can even damage the transmission bell housing. In order to fight this we had EKagrip make some of their patented nickel and diamond coated friction shims. These shims increase the friction between the two components by up to 3 times what is seen with regular steel on steel contact. This greatly increases the load which can be carried. The shims are .008" thick, and do not cause any alignment problems with the clutch / flywheel. Order here
