Red Line Transmission Lubricants are designed to provide excellent low temperature shiftability and improved gear protection at higher temperatures. Efficiency improvements between 1 to 5 Percent are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line transmission oils to carry higher loads compared to petroleum lubricants. The stability of these products allow them to be used for extended periods. MTL® can be used in most manual transmissions and transaxles for both street and racing use unless the manufacturer requires the additional protection of an SAE 90 or the extreme pressure protection of a GL5. In those situations the MT 90 (GL4) or 75W90NS (GL5) will provide good shiftability and synchro compatibility and extra gear protection. Limited slip transaxles may require the 75W90 Gear Oil to prevent limited slip chatter. 75W140NS is designed to help reduce the noise in noisy transmissions and transaxles, while still allowing good low temperature shiftability. D4 Automatic Transmission Fluid and High Temperature Automatic Transmission Fluid provides the gear protection of a GL4 gear oil in an automatic transmission fluid, which is far superior to a conventional Automatic Transmission Fluid. This gear protection makes it perfect for lubricating automatic transaxles and high performance automatic transmissions. The D4 Automatic Transmission Fluid provides the best low temperature shiftability. MTL® provides better wear protection in most manual transmissions which call for an Automatic Transmission Fluid which can be very important in racing applications. MTL® provides the low temperature properties equivalent to a petroleum Automatic Transmission Fluid. All Red Line transmission lubricants provide excellent synchronizer compatibility.

Affordable performance air filter
I was skeptical at first. How can such a quality performance air filter be so affordable? It fits perfectly and seems to perform and look exactly like the other name brand layered cotton gauze, steel meshed lifetime air filter. I sprayed some K&N oil on this thing and it feels like the engine is breathing a little easier now and performing a little better. As with anything new, your mileage will vary.
