This is an absolute must have for your Hyosung! Had it for around one year now, and it works great. Easy to install (P&P) and it delivers on it’s promises!

Installed on RC 2018. The crem de la crem of spark plugs. Engine smooth, power on demand has improved, acceleration unbelievable and a clean start. Worth the money, combine with the NGK caps for optimum performance. Matt

Wow such a huge difference, finally changed this myself. Not too scary. Straight swap for old kit. Didn't even need a gasket. Much sharper gear changes and acceleration. I highly recommend. On a scale of 1 to 10 it's about a 6 in mechanical knowledge. Remember to soak the plates and don't over tighten the bolts. It's a full oil change so have at least 2 litres handy

Easily fitted and noticeable improvement. Highly recommended. Fast delivery to Spain. Excellent service from Marcel

This little piece is beautiful! I went for the gold, and really adds a nice pop of colour to the bike, so now I need to add some more gold to tie in!

Look the mutts nuts , and Marcel had them delivered quickly

received today with the rest of my order will definitely order again in the future

Fitted yesterday, seems to be working well, Delivery by royal mail arrived on time, Very well packaged with other items ordered, Very pleased

Only brought this since I've heard the stock ones on the bike aren't that reliable

Great item fast delivery just what I needed for my bike to get it through its mot thanks
