Denso(4712) IXEH22TT Iridium TT Spark Plug, (Pack of 1)

What can I say screw? Zinn doesn’t fall apart and last long and always fires perfectly

Denso is always a great product. Car running beautiful.

As good as OEM NGK at fraction of the cost. Replaced factory set after 100k, they been worn, but still OK. Engine certainly runs smoother with new set

Truck just hit 200,000 miles changed. All of the plugs car runs like new again. Lots of power just cruises. Make sure to get some anti seize grease for the threads. $5 well spent down the rode

I replaced original spark plugs in my 2021 Mazda CX3 at 97000 mi. Definitely needs to be done as my idle was really rough and gas milage decreased noticably. Took me 15 min or less to replace using proper tools. Theres plenty of videos how to do it yourself online. Only drove 1000 mi on these by now and milage improved significantly and engine works much smoother. Def recommend but I'd like to update this review in a bit. Who knows how they perform after more miles

I purchased 8 spark plugs but unfortunately 7 spark plugs where shipped with additional park of another brand of spark plugs. I have subsequently returned it yesterday

These plugs have transformed my Honda fit 2014 providing great performance for money the money. Definitely recommend
