During the month of August, use coupon code TT10IS at checkout for 10% off Denso's Platinum TT Spark Plugs. If your vehicle takes traditional nickel or single platinum plugs, this guy is a great upgrade. In our recent dyno testing the TT plug performed right along side Denso's Iridium Power Plugs. Though they have the longevity of a standard plug the performance makes these a great bang for the buck!
