Review DARTON 300-039 Big Bore Seal Tight Sleeves For Subaru 86-90mm for SUBARU WRX BRZ
The Darton Big Seal, part number 300-039, is a high-performance engine component specifically designed for Subaru FA20 engines found in WRX, BRZ, and 86 models. This sealing solution is manufactured by Darton Engineering, a renowned name in the automotive industry, known for its commitment to quality and innovation.
The Big Seal is an upgraded alternative to the OEM (Original Equipment Manufacturer) seal, engineered to provide enhanced sealing capabilities and improved engine performance. This seal measures 90mm in length and is designed to fit snugly into the engine block, forming a tight seal between the cylinder head and the block.
Made from a proprietary alloy material, the Big Seal offers superior strength and durability compared to the standard seal. It is precisely machined to ensure a perfect fit and optimal sealing performance. The alloy material also allows for better heat dissipation, which can help maintain optimal engine temperatures and reduce the potential for thermal stress.
Installation of the Big Seal is relatively straightforward and can be done as part of a regular engine rebuild or upgrade. By replacing the OEM seal with the Darton Big Seal, you can expect improved sealing efficiency, reduced oil consumption, and potentially increased engine power and torque.
In summary, the Darton Big Seal, part number 300-039, is a high-quality, performance-enhancing engine component designed for Subaru FA20 engines. It offers superior strength, durability, and sealing capabilities, and can lead to improved engine performance, reduced oil consumption, and better heat dissipation.
