MORE PARTS WILL BE ADDED SOON.....STAY TUNED !

New billet coupler set and dampner for stand-up Hydrospace. On the best S4 since 2007 suggested for engine equipped with 140-160 and 180 HP. The coupler is bigger than the original one and the dampner has been made with stronger rubber and don't breake. A must for engine with more of 110 horse power. I suggest don't replace the original drive shaft with the longer one that fits direct into the engine because this will breake too. retail price € 207.50 + tax

2011 and 2012 IJSBA Pro Ski WORLD CHAMPION , equipped with : Wave intercooler , Wave front sponsons , Wave billet coupler

This NEW intercooler for S4 Hydrospace is very good for 140-160-180 HP kit and it works much better than the old model , it gives a better performance at low-mid and top-end RPM  , also on 110hp is good , we have put the support stainless steel bracket in a lower position for a better center of gravity , also the air flow has been re-shaped for a crispy throttle response , another new feature is the internal cooling elements , they are the same as the ones used in lots of teams at the world superbike motorcycle championship and GP as well . This intercooler is a must for a fast holeshot .
