Got 4 new replacement plugs from E3 on friday, put them in sunday. I really like these plugs. Car feels better, starts easier, smoother acceleration, and more top end power. They feel the way they did when the last set was me was new.

I really don't care if something fails as long as the company responds well. I will have to check mileage when I stop romping around on the car. I usually get 30.5 in the city. In Dallas that means 50% time your going 10mph 50% your going 85mph. It should go up some.

I removed the secondary air filter from my stock air box, replaced the filter and removed the snorkel. It's flows a lot better now, more noise but no drone. That second filter looks like more of an acoustic dampener. Very restrictive. I also cleaned my Mass airflow sensor with MAF spray.
