Customer Reviews

Iridium Power Series Spark Plug, Sold Individually
Excellent quality spark plugs.
Seems to have helped with more power, and smoother idle. It was well over the recommended time to do a tune up on my yota pickup so these were a welcomed improvement. I like the design and performance so far of these spark plugs. I will always try to use Denso direct fit products on my Toyota vehicles.
