Just orderd for my 07 XTX a Pipercross highflow airfilter and a PC III
PIPERCROSS YAMAHA XT660 04> HIGH PERFORMANCE OILED FOAM AIR FILTER (Reference #-2081)
MORE POWER, MORE TORQUE, RACE & DYNO PROVEN
Pipercross foam air filters consistently outperform paper and cotton-gauze rivals to supply air to the engine - even when dirty!
This is thanks to the multilaminate construction used in every Pipercross performance air filter. Layers of varying porosity foam all work together to trap different sized particles.
Next week the parts wil be here, it may take some longer because of the holidays over here in the Netherlands.
When i have the parts i will install them my self, and will program the PC III with a map from the internet.
Whem iam done there wil folow a Dyno run @ Molenaar Racing.
