Denso (5340) ITV22 Iridium Power Spark Plug 1 step colder - Pack of 4
SKU: ITV22-SET
Increased performance with World's smallest Iridium Center Electrode (0.4mm). To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power uses DENSO's patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.
We recommend these 1 Step Colder Plugs for EcoBoost vehicles running modifications with a custom tune ( .028" Gap for Focus ST/Fiesta ST cars, and .026" Gap for all other cars listed below)

Amazing Plugs
Install is what you expect for a spark plug, but i switched to the Denso's per Raffi's suggestion and boy was there a difference between these and the ngk's i was running. My car runs smoother and feels more snappy now. Definitely reccomend the denso for your Focus ST!
United StatesGreat service
I always receive fast , accurate service from FSWERKS . JH
United StatesDenso 5340's
Great plugs.
United StatesAmazing
Works amazing, 100% recommends, especially for speed3's, yes they fit mazdaspeed3's, runs way better, they come pre gapped ar .028
United StatesGreat buy
Switched from the NGK’s to the Denso and I could tell the car runs better. It was also a plus that they came pre-gapped at .28 I would highly recommend
United Statesnot sure if lucky but they came pre gapped. made install a breeze.
United StatesGood rpm , best acceleration , do it
Aiuta parecchio, miglior combustione e miglior ripresa
