Why is the Long Life Denso spark plug more expensive than the TT Denso spark plug? Vehicle info Lexus 2007 ES 350Kenneth T.Jul 06, 2022
Best Answer:Hi Kenneth, I'm pleased to assist you. The TT spark plug features a twin tip, a thin center of 0.4mm, and a protruding ground electrode of 0.7mm in diameter. While The Long Life is an OEM design, made for specific engines and features a special resistor or electrode depending on the OE requirements. It has a reach of 26.5 mm. Click on "See All Product Details" for both parts and you will see the differences. We suggest contacting the dealership with the VIN to ask if you require the Long Life spark plugs. Click on the link below to choose among the options we have available and order at a discounted price while supplies last. I hope this helps.
