Owner reviews for spark plug

Get an icon click type torque wrench from harbor freight when they have a sale. And a deep socket set for spark plugs plus dont buy your plugs on Amazon. Go to rockauto. And buy them there buy ngks also rediitt has a rockauto sub and usually people give out 5%off coupons. Also Do not use cheap aftermarket plugs on your car also you'll need a regular ratcheting wrench and extension. Never use torque wrench to loosen plugs it csn destroy the calibration

There is a noticeable improvement in performance when I cross over into the next country and refuel. This is what my denso iridium plugs look like after 20k km. I had a misfire. New plugs today, and the misfire is gone

You get a better performance if you install a booster plug, DNA air filter and Brisk spark plugs. Great torque from 2000 rpm as a result.

NGK Laser Iridiums will last longer, but those aren't bad per se.

I had to put a new spark plug in mine after only a few hours of use. It had some China branded in it and I switched to NGK. Also propane creates a hard harder to jump spark gap so you generally have to narrow the gap a tiny bit from typical specs when you’re going to run propane. Since I only run propane I went down a little on the gap and it runs flawlessly. I optimize the gap width by seeing which widths responded best to a sudden surge load without hesitating.

NGK Lazer Iridium Plugs is what I got to replace them in my car. I believe those are what Mazda OEM plugs are, but it’s just cheaper to buy the NGKs from a part store.

Yup. They do still exist. If I recall they have the 3800, arguably the best V6 if not the best motor the general ever produced. I hear some of the spark plugs are a total beotch to change. Comfortable car and among the last true “personal luxury” cars. They “were” fairly common 25 years ago.

I also added bosch sparkplugs 4 months ago, and also have some stuttering.

RIP doing spark plugs at home and not hating life.

Good luck doing spark plugs
