🔥 Enhance Performance with Denso 3444 Spark Plug for Optimal Ignition Review

Wrong gap. The outer electrode looked used/worn compared to another set purchased from an auto parts store. Shook my engine badly. Don't buy them. Spend an extra $4 on a connector at your local auto parts store.

Uber is disappointed that the seller didn't post or tell me that a 14mm socket is required to install/remove it! So I had to go and get $5 and waste my time and money on something that could have been avoided! Plugs are installed and work perfectly.

Custom rosette falls on a star. It took me ages to figure out that the plugs I was pulling out were standard 5/8" jacks, but when I tried to use the 14mm jack these plugs use it was confusing. Trial and error finally worked it out. The spark plug fit perfectly in the cylinder. Fired up immediately and the clicking sound was gone. Nice and quiet like the day I bought it. This was on a 2011 Elantra Limited with a 1.8 liter engine (NA).

Bought 4 spark plugs for my 2014 Corolla, the numbers match my car that's why I bought them. We installed them and we were going to go to New York after installing them, but they ran out. My check engine light came on. We have no choice and pay the rent for the trip. Scanner connected, found error P0301 #1. I checked all the wiring, changed the coil and did many other things. I ended up changing connector #1 to Plus #2, the code changed to #2 Miss Fire.

Check clearance before installation! I ordered all the candles from Revain, four in one order and one in another. Four, which turned out to be US made, had the correct gaps and worked well. The one that turned out to be made in Japan (Japanese label on the box) was badly torn. I may have come across a used one that someone returned after messing around with the clearance as Japanese production is usually very desirable. I'm glad I bought a Revain spark plug gauge, the excellent KD Tools 2327…

I bought these iridium spark plugs for my 2011 Prius, these are an exact replacement, much cheaper than the dealer asked for, I can count on them for the next 100,000 miles, my original set lasts over 103,000 miles - still runs fine, once the new kit installed the car is faster and much better, the powerband merges with the highway entrance so the iridium plugs REALLY degrade performance and fuel economy. I saved a few bucks by changing the spark plugs myself, it was a fist and labor intensive…
