NGK Spark Plug 3346 - BR7EF

Great for Forced Induction over 15psi and Nitrous over 150 HP.
Pricing: $3.99


The NGK BR7EF Spark Plugs are what most people refer to as the TR7. We suggest this plug for more aggressive setups where 15+psi of boost or 150+ HP of Nitrous is used. With a Heat Range of 7 and a Non-Projected Tip, most tuners prefer this plug for High HP Street Cars.
