Denso #4504 Platinum T 🔌 T Spark Plugs (Pack of 6) PK20TT Review

These spark plugs used for the first time. I used Bosch and switched based on reviews. Less expensive and powerful, good spark/performance and most importantly, replacement spark plugs, new spark plug wires, a new rotor and distributor cap provided the necessary "cleaning up of my emissions" for my car to pass CA's stringent smog test. If you own a 1993 Volvo 850 with over 400,000 miles, pray every time the car passes the smog test.

Although my car's service manual lists iridium spark plugs, I decided to try these spark plugs as Denso stated they were fully compatible with my car. Idling is much smoother and acceleration is greatly improved. It's only been a few weeks, but we'll see how they fare in the long run. However, the iridium spark plugs lasted nearly 200,000 miles (still worked well but were replaced for peace of mind).

The Toyota 1MZ 3.0 V6 uses iridium spark plugs. These platinum candles really work and will get you 60,000 miles. I forgot to look what kind of plugs I really should have gotten for this. The gaps on the candles are over. 1 looked like it had been dropped and there was almost no gap lol. I replaced all the plugs with .041 and continued on my way with no problems. I really recommend that you buy iridiums, they last a lot longer. Nobody likes to build transverse V6 spark plugs, haha.

I'm not sure how to write this review, they say the spark plugs work with my Jeep Liberty. I know they are not iridium and I have done nothing. Research and this is the first time I have freedom. So you can say that this is partly my fault. I was just saying these spark plugs will work on your jeep. Long story short I replaced the NGK iridium plugs with these plugs in March, not even 5000 miles on these new plugs and already I'm having serious misfires, my gas mileage is terrible and when I sit

I only give 4 stars but I really deserve 5 stars but because the person who told me to order it and it will do a good job did a job that I am very happy with , but one day they took care of those that need replacing didn't go beyond what needed to be done, for which I'm really grateful. I thought I had to buy another car, but at the time I didn't want to. After the replacement, the defect ran like a new car. I no longer had to worry about running a red light as it no longer spat or stalled when
