Spark Plug Platinum TT - Denso Platinum TT NP-4504

Spark Plug - Platinum TT | Platinum TT - Twin-Tip Technology Design with Platinum Center Electrode and Titanium Enhanced Ground Strap | Gap .040

Spark plugs ignite the compressed air/fuel mixture in each cylinder, and their condition directly affects combustion efficiency, fuel economy, and emissions. Signs of worn plugs include: difficulty starting, a rough idle, a hesitation or misfire under acceleration, reduced fuel economy, or a check engine light with misfire codes. Replace spark plugs on schedule - new plugs restore clean ignition performance and can noticeably improve fuel economy.

Denso Platinum TT (Twin-Tip) spark plugs feature platinum center and ground electrodes for extended service life and reliable performance. Engineered to OE standards with service intervals up to 60,000 miles.
