Q:are these already gapped ?
Jy'warrick M.
A:BEST ANSWERHi Jy, I'm pleased to assist you. According to the Denso website, in most cases, their Iridium Power plugs do not need to be gapped as they come with a factory-preset gap. However, it is recommended to review the specification chart if the gap needs to be adjusted, it should be done with extreme caution using a calibrated gapping tool to avoid damaging the spark plug. You can click the link below to continue ordering today while the part is in stock. Happy shopping! https://www.carparts.com/spark-plug/denso/set-np4703-8?can=CPGG4850_CSQA_20240108 Show less
