【Price Reduced】 This is a used m+ XA-EOR-0001 Friction Free Module Engine Oil Reactor. It originally cost nearly 30,000 yen. Here's a product description: Inside a running engine, engine oil is exposed to extremely harsh conditions, including friction and shear between molecules, continuous friction with filters, and localized pressure from pistons, crankshafts, and cams. This generates a large amount of static electricity in the oil itself. The electrification of engine oil causes the formation of highly reactive molecules called free radicals, which spoil the original lubricating performance. Free radicals accelerate oil oxidation, shortening its lifespan and also causing sludge. The Engine Oil Reactor is based on the principles and technology of the m+ FRICTION FREE MODULE, with tuning optimized for suppressing the electrification of engine oil. It allows the oil to perform to its full potential and smooths engine rotation. By reducing the generation of free radicals, it suppresses oil degradation and reduces the decline in feel during its service life. It also suppresses sludge and protects the engine itself. Recommended for: * Owners who prioritize rotational feel * Owners who want to suppress oil degradation * Owners who want to take good care of their engine It can be used on any vehicle and is connected by bolting it to a screw on the engine block or cylinder head (head cover) near the oil filter. The effect is semi-permanent. After installing the product, you may feel that the engine braking is weaker, so please be careful about your following distance. While this product alone is effective, it is especially recommended for customers who have already installed the m+ FRICTION FREE MODULE 4-LAYER or 10-LAYER and are experiencing its effects, as it provides a synergistic effect on the engine oil.
