      Comments about Bosch OE Fine Wire Iridium Spark Plug:

      Easy the best purchase of my year. Why? Needed plugs badly and the rebate broke the deal. Game changer. SIX PLUGS with coupon and then the rebate. Now they owe me 1 DOLLAR. Don't forget about the quality.

        Comments about Bosch OE Fine Wire Iridium Spark Plug:

        These spark plugs were listed as direct replacements for the NGK plugs that came OEM from Toyota. After ~120K miles, the NGKs in my wife's '02 Highlander V-6 were due for replacement. These went in like any other spark plug replacement and the change in performance was noticeable (and my wife is happy again :)

        On a side note: for those with this vehicle or similar, be prepared to remove the intake in order to replace the back 3 plugs (near firewall). Replacing the plugs was easy, removing/replacing the intake was NOT.

          Purchased online through Advance Auto Parts with 20% OFF SALE. Paid for and picked up within an hour at my nearest store. Toyota manufacture say change every 100,000 miles. I like to change mine every 50,000 to keep my engine running smooth and continue getting great gas mileage.

            Bosch says they guarantee your happy or money back. Well I'm happy. The car had a sticker that said only use iridium, don't gap, well I replaced mine at 106k and it purrs like a kitten. Trust Bosch!
