## Description

Iridium and platinum technologies combine with Denso’s 360-degree laser welding process to create a plug with a lifetime over 100, 000 miles. TT or Twin-Tip technology promotes spark energy concentration and explosion, which translates into improved acceleration and economy. Iridium TT feature the world’s smallest 0. 4mm iridium center electrode and 0. 7mm needle tip ground electrode, which minimize spark interference and maximize ignitability, resulting in better power, torque and fuel economy. Denso’s patented iridium alloy has the highest iridium concentration, making it more durable and producing a dramatic improvement in spark plug life.

Review: Best plugs ever! - 95 Accord EX owner. The shop I use chose to put copper NGK's in an engine swap. They were WRONG! These are made for this F22b engine! I've tried other iridium plugs and they were ok (couldn't tell much difference in engine response). These feel like the gas is double octane. They burn hard and give the proper ignition to each cylinder. It only stands to reason that if your older car needs a boost, this is the efficient way to do it, and if your new car should be better, make sure you get these! (Also, my seller was amazing at pricing!)
Review: Misleading - Beware , that $14 is for 1 plug , not 4
