Review: High quality long lasting plug! - Why did you choose this product over others?: I wanted a 'long lasting high performance plug for my Thruxton R and this appeared to fit the bill! I changed several things at once (stale fuel, redex, plugs, air filter so it's not possible to say I 'noticed a marked improvement' just because of this!
Review: Super Plugs.👍👍 - I got fed up keep changing plugs on a Yamaha MT07 Tracer. Every time you have to change the plugs you have to half strip the bike. 😖😖😖. So now I have these plugs fitted which should last at least THREE +times longer. 👍👍👍.
