Review on 🔧 Enhance Engine Performance with Fel-Pro ES 72481 Spark Plug Tube Seal Set by John Carter

Guaranteed to fit, does not fit! When replacing gaskets and valve cover gaskets, the cone seal is installed last. After removing the cap, the plug gasket was the wrong size. I use my car to earn money. Had to order an emergency one day delivery for an Infiniti OEM case including gaskets. $250 + 8.75% tax. Unfortunate to put it mildly! Thank you Fel-Pro. This mistake cost me $250 in sales and $270+ per part = $520. Round seals shown above.
