They dont look better dan the oem ones but they seem to be doing good work so far.. Hope they last a while.. I am getting a misfire but i hope its a different issue.. Goood value and nkg seems like a great brand for the 2jz engines..
Good plugs, positive process for time, cost, and mindful packing.
Can't speak to the experience of what's needed to replace the spark plugs in a Highlander (ok, bleeaaaahh), but the plugs were gapped correctly, packed correctly, arrived quickly, and were very reasonably priced within the eBay-verse. The NGK plugs were what was recommended by our Toyota mechanic.
