Welcome to the HEL Performance range of high-quality, dependable and unrivalled oil system components. Our widely embraced, race-winning products have not only secured victories on the race track but have also been rigorously tested on the open road.
What sets us apart is simple yet significant; we handle the entire CNC machining process in-house for our complete range of oil system components. This gives us full control over the manufacturing process, leading to exceptional quality and faultless products. This commitment guarantees longevity and unwavering durability, even when used in the most demanding and challenging environments.
The HEL Performance thermostatic oil filter sandwich plate is available in various configurations, offering a range of center bolt options and thermostat temperatures to cater to your specific needs. Equipped with a built-in thermostat, this sandwich plate ensures that your engine oil flows to the external oil cooler only when it reaches the desired operating temperature. This innovative feature not only promotes a quicker engine warm-up but also provides added safeguarding in cold weather conditions, setting it apart from non-thermostatic alternatives.
Once your engine oil reaches the pre-set temperature (82°C, 92°C, or 102°C), the valve opens, permitting the flow of oil to the external oil cooler. This results in a controlled reduction of oil temperature as it circulates through the external oil cooler, which is often equipped with cooling fins and/or with the addition of a fan to facilitate heat dissipation. Around 10% of the engine oil circulates through the oil cooler at any given time, this ensures a continuous flow that prevents air pockets and safeguards against thermal shock to the system. The surplus oil is channelled back to the engine or transmission through the internal bypass system, promoting faster warm-up and eliminating the risk of overcooling.
Our oil filter sandwich plates feature M22 x 1.5threaded inlet and outlet ports and can be easily adapted with M22 x 1.5 to -8 (AN08) or -10 (AN10) male adapters, ensuring compatibility with a wide range of AN fittings, hoses and adapters. The threaded center bolts are manufactured from high-quality stainless steel and are available in M20 x 1.5 or 3/4"-16 UNF sizes to accommodate most common spin-on oil filters.
Designed as a universal product, our sandwich plate can be mounted on various engine blocks. To determine if it's the right fit for your application, please refer to our technical drawings which can be found in the downloadable user manual.
