Description

NGK LMAR8F-9 spark plugs are engineered for engines running elevated boost levels or aggressive ignition timing where thermal stability is non-negotiable. The wide heat range prevents the common failure modes that plague standard plugs—fouling under light load and pre-ignition under full throttle. If you're serious about consistent power delivery and reliability across varying operating conditions, these plugs deliver the thermal management your engine demands.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
