Spark plug NGK or OEM BMW

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

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.

use NGK spark plugs, the best ones are the PFR6Q

Pick up some genuine Audi R8 Red-Top coils (not kidding, much lower failure rate) and some fresh NGK Iridium spark plugs.

I had this very same problem where on my 07 V6 the acceleration and power was off. I had replaced my spark plugs with NGK Iridium plugs and after dealing with the horrible performance I decided to change them out for OEM platinum (copper) plugs. This made a huge difference and could immediately tell a night and day difference. Regained the torque and power that was missing.

Went with NGK spark plugs that was bundled with some generic wires and coils, not ideal but it’s all I could afford at the moment

I learned that proper, very hard to tell, NGK knock offs even existed after I was bitten by fake ones off Amazon. The porcelain around the center electrode broke off and went through the engine.

I have installed brand new NGK sparkplugs and Bosh ignition coils...but the cylinder 1 misfire does not move or is resolved at all.
