DENSO (IK20TT) 4702 IRIDIUM SPARK PLUG For Acura
-creating the explosion which makes your engine produce power.
-These small but simple plugs create an arc of electricity across two leads which are not touching.
-They are close enough together that electricity can jump the gap between them
Below are the vehicles that fit
ALFA ROMEO 1995
Iridium and platinum technologies combine with Denso’s 360-degree laser welding process in Denso Twin-Tip Iridium 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. Machine rolled threads prevent seizing or cross threading during installation and removal.100% pre-fired to assure the highest quality possible. Purified alumina powder insulator provides exceptional strength and thermal conductivity. Five rib insulator prevents flashover. Copper-glass seal bonds center electrode and insulator for a gas-tight seal.
