This is the best quality one I found for my car that was also OEM/Denso! My car was shaking a lot and burning every ignition coil. I gave four new Denso Spark Plugs, four new Denso Coils, and changed out two wire terminal harness. Good as new!

I'm using the spark plugs in my 1993 Lexus SC400. Previously, about 140,000 miles ago, I used the DENSO Iridium version of the same spark plug. They still had the 0.043 gap as when they were installed. The owners manual called out the DENSO Platinum plugs, so I purchased them. The new spark plugs are installed and working great.

Let me start off by saying I plug the car into the website down to the T. Make model engine size and all. The plugs them self seem to be of good quality. A few things to note. All of the plugs were opened and the boxes were smashed. When I asked the employee about it, another older employee jumped in and said aggressively they are brand new!! So I took them home against my better judgment and when I went to install them they were the wrong plugs. However, it was the website that gave the wrong plugs not the employee's. The plugs were for a 2017 Toyota Corolla LE

Ap3923 plugs suggested life is 50k+. Previously purchased autolite plugs have gapped at recommended gap (.44) when replaced at 35 k in a camry whereas the same plugs (allegedly) had eroded Platinum tips on 3 of 4 plugs gapping greater than .50 on 3 of 4. Either the plugs purchased (2020) were defective (lower quality) or counterfeit which as suggested on YouTube have similar problems. What's interesting the recommended plug for a '98 camry is 3923 (mid temp) whereas denso and ngk recommend a mid high temp plug.

I was surprised by the fact, I didn't have to adjust the spark gap on these plugs. Installs easily on my Neon. The last set I purchased were a different brand and I had to adjust the spark gap on that series before installing. Again, I was plesently surprised.

I have used these before on my Chevy Silverado. They produce more power than E3 and Accel racing sparkplugs. I own a Chevy racing El camino and with accel racing sparkplugs and a 2012 Tahoe with MSD coil packs, sparkplugs wires and E3. you can not use these with cheap 7mm sparkplug wire. They burn to hot !!! above I will recommend these sparkplugs. you need 8.00 mm and above wires high end coil packs. it's like putting holley 750 in 4 cylinder car and not upgrading the engine.

Very dissatisfied with the such short life these plugs had , didnt even last 5,000 miles ,and all the electrodes burnt right off in my brand new rebuilt jeep engine, all burned the same but burnt up ! Also had a pair in my street bike never had a problem before with cheap plugs until I ran these . I was almost stranded cause one of the fouled, limped home on one cylinder! I would not recommend to anyone!!!

These plugs are so bad due to their low quality. I thought I lost my engine yesterday. Only about 20 days and 500 miles since I installed them. Just on the highway on the way home at 65 MPH yesterday car started running not on all cylinders, it was running so bad i was sure the engine was finished. Just made it home. After cleaning up the mess it made on the top of the engine I found the top of the spark plug had exploded and the central terminal had ejected from the plug, so it was like the spark plug wasn't even installed in the cylinder, hence the mess. When I say the top of the plug exploded, I mean it really did exploded, it even blew up the spark plug boot that was on it. Granted these plugs did give better low end power than the stock plugs, but based on how they failed, they are clearly low quality and not reliable enough for daily use. Please save your money and time.
