Product reviewsNGK DCPR9EIX Spark Plug

problem solved

I can't offer an excuse or even an explanation for not changing the plugs in my Aprilia RSV 1000R since 2005, but that was what I did (or failed to do)
Eventually, the poor old girl started firing on one cylinder, so I was forced to check the plugs.
Typical Italian design, this involved removing the fuel tank and airbox etc.
But once done, what a difference !
Should have done it years ago (no really)

PS
I have changed the oil regularlyRead full review...

Instant improvement

These plugs just work. Spark is more consistent. Engine runs smother with good pickup.
