Please note:Supplied in a pack of 4 plugs.
Easy to install. Nothing really noticeable over the Stock spark plugs at low speed but, once moving - acceleration, performance improves. Fitted as a precursor to my 3rd Service. Very happy & totally recommended especially running FPM375 - 400R etc. MAGIC MOUNTUNE DOES IT AGAIN !!
Excelente calidad como siempre
After looking at new upgraded spark plugs and seeing the reviews on here and also that they come pre gapped ready to fit. I made the purchase and what a difference in the RS mk3, it runs so much smoother, on idle and through the gears. It gives me peace of mind running extra power and delivers it much better, feels a lot faster! They do exactly as it says. I can't rate these plugs enough, I would highly recommend for the price and ease of fitting.
