Owner reviews for spark plug

Modern Ford engines tend to work best with Motorcraft or NGK spark plugs.

Have some I'm waiting to try out in my turbo 4age after using bkr7e ngks for years. I mean denso is an A1 company and they offer heat ranges colder than NGK so probably worthwhile for my turbo engine.

use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.

Champion iridium. Champion makes the Mopar plugs. It's the closest thing to the original plugs without having to spend $30/plug.

NGK iridium for plugs.

Almost 130.000km on the odo, had a bad spark plug recently but it is not know why or how (could just be a bad one) but overall the engine runs fine and stable.

I have an 02 4runner with 289,500 miles. I've had it for the last 106,000. Replaced the timing belt/ water pump twice. Replaced spark plugs twice. New brakes a few times.

Used those for the same setup with no drama, stock gap measured at 0.026". I've run lots of different plugs....honestly, they make zero ****ing difference IMHO on my peasant IS20 and 38 1.8 sLOw OTS Uni tune...

Also I would stay away from Brisk ER12 spark plugs since they require higher change intervals (And risk of damaging coil packs) @ 3-5K miles as opposed to NGK R7437-8 or NGK R7438-8 @ 10-15K miles.

With almost every car, using OEM plugs is the way to go. The one brand to ALWAYS avoid is Autolite. They are extremely poor quality and I have never seen them work long enough to justify the cost saving.
