Metaloflex Cylinder-head Gaskets Elring cylinder-head gaskets are high-tech components used in modern combustion engines. As key components, they help to ensure that engines run efficiently, reliably and economically. Developed by ElringKlinger, Metaloflex is a globally recognized brand of innovative metal layer cylinder-head gaskets made of beaded, elastomer-coated spring steel layers. Multilayer steel cylinder-head gaskets are available in various bead designs and with a different number of layers, depending on the OE specification of the respective car manufacturer. Metaloflex gaskets may be of single or multi-layer design depending on the application. Thanks to the modular design elements, this sealing system can be individually adapted to suit the requirements of the specific engine. This technology avoids the need for time-consuming, costly iterative processes whilst guaranteeing maximum engine design flexibility.

Product Features:

• Produced from spring steel for long-lasting flexibility of beads
• Thermal stability up to 600F
• Full or partial FPM surface coverage of head and block layer for micro-sealing of liquids and combustion gas – extended service life
• Heat treatment of functional layers further enhances gasket durability and this technology is exclusively applied to ElringKlinger metal gaskets
• Tightening instructions provided with each gasket for perfect results

All Nissens oil coolers are manufactured to meet OEM specifications and depending on application are provided with anodic coating, built-in thermo bypass, and/or pressure bypass.

Product Features:

• Meets or exceeds OE specifications
• Manufactured using advanced lightweight materials
• Low weight and design space requirements
• OE Style connections

Bosch Crankshaft Position Sensors provide Accurate Detection of the engine speed: the engine speed is the main control variable for the ignition timing.

Product Features:

• Precise digital measurement of rotational speeds
• OE-technology quality components Developed and manufactured to very fine tolerances
• High resistance against external interference

Optimum engine control is based on current, exact information from the powertrain. This information is provided by various sensors. The engine control unit uses the camshaft position sensor to record the exact position of the camshaft. This increases power and supports emissions reduction at the same time. Supports reduction of fuel consumption and hence CO2 emissions. Quick-start capability due to TPO function (true power on). Immediate recording of camshaft position for rapid valve control.

Product Features:

• Robust design with Twist insensitive mounting (TIM)
• Reliable digital measurement and wide temperature range
• High accuracy and long service life

MAHLE Original piston rings lead the way in ring technology and innovation for the Aftermarket – after all, MAHLE is the largest manufacturer of piston rings in the world. MAHLE Original rings are at the forefront of light vehicle piston ring technology. Extensive OE connections mean that MAHLE Original rings have the technological edge. Things like the CP-20 oil ring, narrow compression rings, steel compression rings for gasoline engines, low-tension oil rings and coated compression rings for diesels all came from the OE. The MAHLE Original performance line proves time and again that it should be the ring of choice under every hood – regardless of the application. Grey cast iron or ductile iron was traditionally the material of choice for automotive applications – today, steel is preferred over iron by more and more engine builders. Steel compression ring technology has been used in heavy-duty applications for over 30 years. That know-how has become essential to the design and engineering of today’s automotive engines. Steel piston rings offer higher tensile strength, higher yield strength, greater fatigue life, and greater hardness while still offering a lower ring mass. These factors lead to better stress resistance, reduced groove pound-out, longer service life, better conformability, superior oil economy, and improved blow-by control while still lowering friction.

Product Features:

• Ease of installation makes them the premier choice for rebuilders everywhere.
• The CP-20 rings can withstand the harsh operating environments in today’s engines.
• The CP-20 consists of a barrel-faced top compression ring for better seal and quicker break-in, a reverse torsional twist second ring for better oil control
• The CP-20 design oil ring that is easier to install
• Chemically polished for better oil drain-back
• A 20 degree ear angle to ensure side seal around the ring
