Product Details

Iridium Long-Life Spark Plug (Semi Truck) by Denso®. Denso's patented Iridium alloy is more durable than even Platinum, allowing the center electrode to be shrunk to only 0.7 mm in diameter. This produces a dramatic improvement in ignitability and spark plug life.

What can I say other than a Denso product? Great price from TRUCKiD, great customer service. These are the spark plugs for my wife's Honda. Replacing originals after 110K miles. Thank you TRUCKiD!

Beware of Shipping Charges!!
The spark plugs arrived in broken box but they work as required by my vehicle. Could have purchased them locally but since I had an order in thought that they could be included for the convenience. My mistake, however, when I found that TRUCKiD charged me $297.00 for shipping, that is right $297.00 for shipping. Be cautious when buying from TRUCKiD as they have the ability to charge astronomical amounts for shipping and you are not aware until the order is placed and can not be cancelled.

Great Plugs
Great spark plugs at the fraction of the price compared to the car dealers or anywhere else for that matter. This was my first purchase from Denso, but definitely not the last.

Denso® - Double Platinum Spark Plug
These are quality platinum spark plug, easy to install, and the performance of the Acura TSX improves a lot. The price seem to be very reasonnable.
