UPS stopped by today and dropped off several sweet things from ECS Tuning:
Just installed 6 new Denso Iridium Spark Plugs. The install was not to bad. Took me a little while to figure how to get the the left and right coilpack closest to the front of the car off. Finally figured out with the help of my wife that a silver intake piping could be remove with a single bolt removed from either side. After that I was in and out of the garage within a hour. The old NGK plugs actually didn't look that bad, but I do have to say that it seem like my engine revs a little faster and smooth with the new plugs installed. With the bipipe, spark plugs, and air filter, my B5 Audi S4 is feeling very strong right now. We will see how the MPG has change why I take a little trip this coming forth of July weekend.
**Update** went on a 300 mile round trip averaging 28.5 miles per gallon. Not bad for a 300+ hp car.
