    Good plugs, great price.

    These are original equipment on my Toyota Tundra so I went with this brand since the odometer is showing over 110,000 miles and I’m not sure when they were replaced. Installed the new plugs and truck runs like a champ. A bonus was the price, since they were not as expensive as the local auto stores.

    Better packaging would help

    I received these spark plugs in the mail with poor packaging. Some of the boxes were crushed and one of the spark plug was completely out of the package free floating. I have fears that the porcelain maybe cracked. I would hate to spend my time installing these spark plugs only to find one or more defective. Also, the items had the same part number but did not match the picture posted in the listing.

    2014 Toyota Sequía SR5 5.7L V8

    These are the exact OEM plugs that came in my 2014 Toyota Sequoia SR5 5.7L V8. Same part numbers as the original OEM plugs I removed from the engine. The engine runs smoothly again!

    Excellent OEM replacement spark plugs for 4runner v6

    This was an excellent replacement (better than original since this was iridium) and it bolted into the v6 without a hitch. Bonus: I have 2 leftover plugs (since this was an 8 pack) for the next tune up. Highly recommend.

    What a great deal for Toyota OEM spark plugs!

    Great OEM Denso product (exactly the same spark plugs that were original equipment) at a fraction of the cost. My truck runs great after putting the in my 5.7 Tundra. 100% recommend!
