NGK Ruthenium HX Spark Plugs for Civic FK8/FL5/DE5 Acura Integra Type S/CV2 Accord 2.0T & 1.5T Civic

JSR Researched & Developed, these plugs are the ones for your High-Performance K20C1, K20C4, and L15B Motors.

These plugs are hand gapped for up to 716WHP as seen on our Shop FK8. No Modification Required! Simply Plug and Play.

Rock Auto nor Autozone offer this type of service.

One set of (4) plugs is included in every plug order.

NGK Ruthenium HX is designed for newer Turbo Charged engines that demand high ignitability. Projected Square Platinum Electrode (PSPE) design promotes spark energy concentration and ignites a wider range of air-fuel ratios, offering improved performance in rich or lean engine conditions. 0.4mm Ruthenium alloy fine wire center electrode and 0.8mm platinum fine wire ground electrode. Trivalent metal platinum provides superior anti-corrosion and anti-seizing properties. Corrugated ribs prevent flashover. Pure alumina silicate ceramic insulator provides superior strength and better heat transfer. Copper core aids in heat removal.

Ruthenium is the next level 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 lasts 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

Do not attempt to gap these plugs, they are pre-gapped.
