Designed To Increase Horsepower And Acceleration While Providing Excellent Filtration Lifetime Air Filter With K&N Million Mile Limited Warranty® The World's Best Air Filter Simple Drop-in Performance Washable And Reusable Emissions Legal in all 50 US States Will NOT Void Vehicle Warranty The K&N FilterCharger® air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. Our automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. The secret to our success lies in the unique characteristics of our filter medium that was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. We just wanted to win races and stumbled on a cotton filtration technology destined to be great. Our high flow cotton gauze air filter is washable, reusable and built to last for the life of an automotive or motorcycle engine. K&N air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration in addition to protection from the dirt and dust of off-road racing. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle. Learn More

Multiple Spark For Cleaner Burn Smoother Power Heres a theory almost anyone can buy into: more sparks per combustion cycle help extract every last bit of energy from your fuel. Theories are fine, but weve seen a lot of them disproved in the real world, so we tested the MSD 6AL multi-spark discharge CD. On our chassis dyno, our 912E gained a bit over 10 more horsepower after we installed an MSD6AL 909926 CD. That was more than we expected. On the track, we installed a 909926 on a 912E, and the driver was able to cut a full two seconds off his previous lap times. In fact, he set a new class record. MSD has exceeded our highest expectations and we found other benefits beyond the horsepower increase. You also get a smoother-running engine and improved throttle response as well. The way it works is shown in the graph above. Instead of one spark, the MSD unit sparks continuously through 20 degrees of crankshaft rotation to burn all the air/fuel mixture. The 909926 features an adjustable rev limiter you can set to 6000, 7000 or 8000 rpm. Adding the RPM Module Selector allows you to adjust the limit from 6000 to 8200 in 200 rpm increments. The 909926 can be used on all 12-volt Porsches, is street legal in all 50 states. Note: Cars with electric tach need the Tach Adapter). MSD ignitions require hi-spark coil's. For All 12 Volt Cars.

MSD Tach Adapters are necessary for all Porsche® Vehicles with a electronic tachometer. Choose the correct one based on your type of distributor. Learn More
