Spark plug NGK or OEM FORD

If you have a bike that fouls plugs easily, particularly with condensation, the pointy electodes of an irridium plug will still spark. My XV535 would get regular plugs wet with fuel and condensation in winter and then refuse to start. Started reliably on iridium.

I personally run NGK without any issues.

these work fantastic.

You can check the forums and it'll say the same thing your asking . It comes down to personal reference ,everyone (including myself ) that I run with in our 3rd gens we run NGK . Just make sure they are dual pronged and gapped correctly and you'll be just fine .

Use NGK iridium and you will have no problems.

I went with NGK iridium's. The "book" says they should be replaced at 100k. I mostly didn't want to have to fight with them at 100k miles to get them out.

I run usually one of 2 brands. Brisk or NGK both iridium. And both are 1 step colder than stock.

Last time I went Bremi coils and NGK Laser Platinum plugs.

2005 CVPI...180,000 mi....spark plug blown out of head. The Crown Vic was purchased at auction for $4200 a bunch of years ago with 100,000 miles and was very good to us until about a week ago...original engine, suspension parts, transmission and very few repairs.

I used the NGK plugs once and kept getting a pretty bad hiccup under hard acceleration.
