All Plugs are pre-gapped to .020
PROVEN TO ADD POWER
Tested all the way to 614whp flawlessly
Want an instant hp gain. How about a full bolt on Fk8 running on 93 octane made 5whp more by simply installing these plugs. These plugs are using the same material that HKS spark plug upgrade and they charge 30 dollars PER PLUG. That’s 120 per set!
Ruthenium is the next material in spark plugs. They not only handle heat better they are more conductive. This gives greater spark capability under high boost pressures. Also creates less strain on the ignition system. Often people go to a copper plug in order to get the great conductivity that a platinum or iridium electrode can’t provide but a copper plug wears out fast in comparison.
Another great thing about ruthenium is it last longer than iridium. Also these plugs have a unique design called PSPE on the ground strap. Projected Square Platinum Electrode. This design is specific for Turbo and supercharged applications. Higher fuel burn stability under high combustion pressures, more complete burn , smoother engine response, better spool, horsepower and longer lasting. There’s really no downside.
All plugs are sold in sets of 4.
Torque the plug to 16ft lbs
All plugs inspected before shipment
DO NOT TRY TO RE-GAP THESE PLUGS THE TRADITIONAL WAY. YOU RISK DAMAGING THE PSPE GROUND ELECTRODE!!
