Review on 🔥 Denso PT16EPR-L13 Double Platinum Spark Plug Review" by Dan Tsourvakas

DOUBLE PLATINUM DENSO spark plugs (made in Japan) come with a factory preset gap of .060 and MUST be readjusted to engine manufacturers specifications (.054 for 4, 6 liter FOMOCO engine, SOHC). After careful re-spacing, cone plugs should be installed without the use of anti-seize fasteners and torqued to 12-15 ft-lbs. (144-180 in-lbs) for proper compression sealing and maximum heat transfer. The DENSO electrode design provides a strong solid flame front for an excellent combination of performance and fuel economy, and the dual platinum electrodes should last 80,000 to 100,000 miles reliably. After carefully installing the DENSO spark plugs, my wife and I noticed that the engine ran more smoothly and that fuel consumption increased slightly.
