Red Line MTLV GL-4 Gear Oil

Red Line MTLV GL-4 gear oil is recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified. This high-performance gear oil offers quicker shifts, improved coefficient of friction, and better gear protection. It also eliminates notchy shifting, even when cold, and has a less slippery low sulfur formula that's compatible with brass synchronizers. Furthermore, Red Line MTLV GL-4 gear oil remains stable at high temperatures in performance applications. Additional attributes: * Satisfies the gear oil viscosity requirements of 70W and 75W * Low sulfur formula lacks the reactive sulfurs found in most GL-5 oils that cause damage and is safe for brass synchronizers * Popular in Toyota/Lexus LF 75W, BMW X-Drive and other transfer cases transfer cases calling for Shell TF0870 * Recommended for Mercedes 235.10, Dodge/Fiat BOT 350 M3, GM BOT 303 mod, Toyota/Scion Manual Transmissions Gear Oil LV, VW/Audi and BOT270A Graziano Transaxle for Aston Martin, Audi and Lamborghini * Low fluid friction to improve power transfer

NGK Iridium IX Spark Plugs

NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs—and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is the hardest metal used in spark plugs today—six times harder than platinum. This allowed NGK engineers to reduce the voltage requirement for a spark. Iridium IX plugs are available in more than a hundred configurations for universal and vehicle-specific applications.

Boyesen Rage Cage Replacement Reeds

Maximum snowmobile power is achieved by keeping your Boyesen Rage Cage equipped with fresh reed petals. These replacement reed petals are one of the critical aspects of why the Rage Cage works so well. In order to keep your Boyesen Rage Cage performing at peak horsepower and acceleration capacity, you'll need to change the reed petals at least two times per season depending on how much and how hard you ride. The replacements feature a carbon fiber top petal that has excellent response characteristics, providing improved acceleration and stronger throttle response; they're designed to operate specifically with the Rage Cage Reed air intake system. Boyesen engineers craft and hand-tension every Rage Cage replacement reed petal set to work optimally with each respective parent Rage Cage reed assembly to create the performance advantage that the Rage Cage is known to produce.

Boyesen Carbon Tech Reeds

Don't settle for anything less than the best. Boyesen Carbon Tech reeds are made from aerospace-grade, 100 percent carbon fiber--meaning they're long lasting and give better performance. They bolt directly to your stock reed cage without modifying anything else on your intake system and are available in different reed petal tensions to suit the track and your riding style. Reed petal tensions: * Low Tensions (LT) improve power delivery in the lower rpm ranges and are best suited for increasing response and initial acceleration * Mid Tensions (MT) improve power delivery in the mid-range and are ideal for increasing the overall power delivery of your engine * High Tensions (HT) improve power delivery in the upper rpm range and increase maximum output.
