Spark plug BRISK or OEM Honda

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.

I use a Brisk n17yc.

Get a Brisk spark plug. Worked for me

Been using the cheaper Brisk brand and never had an issue for 20k miles.

Eu tenho dois Honda Jazz. As manutenções são super baratas e os carros nunca avariam. Melhores carros de sempre... Até chegar à altura de trocar as velas... Sim, são a 40 euros cada. Preço normal.

Using the muzzler has stopped mine needing the spark plugs changed / having a cylinder go out every 6 weeks.

Right before i changed the map I also swapped spark plugs (brisk er12s). Since it started the rough vibrating, I’ve inspected spark plugs and coil packs, changed the coil pack grounding to a ground kit, cleaned the MAP sensor, and even tried throwing some liquimoly valve clean in it.

Brisk are fine. You have to check them about every 5,000 miles. And change out sooner than other brands.

What plugs you're using may help. In my experience not all plugs are created equal. Brisk, for example, last maybe 5-10k miles before they're garbage. Whereas I can run NGKs for 15k+.

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.
