Denso High Performance Spark Plugs (Pack of 6) for 3.3TT V6

Everyone knows the 3.3L Turbo Stinger spark plugs are misfire prone and require replacement or regapping for higher than stock power levels. BMS suggests the Denso 5346 (or 5347 “2-step” colder plugs for highly modified vehicles) high performance spark plugs for all factory and tuned 3.3L applications gapped to 0.022″.

• 0.4 mm iridium center electrode: world’s smallest diameter that maximizes firing potential
• U-groove and taper cut ground electrode: provides faster spark flame growth and lessens heat quenching
• DENSO patented 360 degree laser welding process: ensuring exceptional quality bond and structural strength with the iridium center electrode
• It is recommended to gap these plugs to .022
