What brand of spark plugs do you like?

Question

I always used the NGK's with no problems.

Answer 1

I like Bosch and NGK.

Answer 2

I use the bosch platinum 4s but if I could afford 20-30 dollars a plugs then I would use Pulstars

Answer 3

It's best to stick with the motor application's recommendation. Ford Motorcraft, GM, AC-Delco, etc. Two cycle motors love NGK's I use them in lawn mowers and lawn tracters. E-3's work well in four cycle small lawnmower motors. In my opinion multi ground gap spark pulgs are a joke in any motor. All motors today have electronic ignition and they respond well with wider gaps and a single ground electrode. Iridium last much longer them platinum tipped plugs as iridium melts at 2443C. Platinum melts at 1773C.

Answer 4

I am an avid fan of NGK, they are in everything I own from all of my cars to all of my motorcycles. they are far the best plug out there.....

Answer 5

depends on what vehicle, i used the ac delco on chevy that works pretty good.  

Answer 6

well then use what you have best luck with.... ive used ac with chevy motorcraft with ford... ngk with small cars and bikes

Answer 7

I normally stick to the spark which came with vehicle, or which is listed in the owners manuel.

Certain Spark plugs will cause engine miss fires even when the parts store say they can be used, an Example VW has a history of engine miss fire, when the spark plug was not a factory one. Because of resistence, heat ranges, depth of the plug itself, and components used in the manufacture of the spark plug itself.

Answer 8

Bosch platinum 4, more probes to create more spark for a better burn of fuel.

Answer 9

i always buy what the factory calls for.in my case since i have a gm, i buy ac plugs.
