EK9 + Mfactory gearing..
i ordered the "pipercross filter service kit" from demon tweeks, in the picture u see 2 yellow containers in front of a box, they look like aerosol cans. i received a small box with one econtainer in it "dirt retention additive", so first i need to ring them tmo, but on the container i got it says to clean the filter in petrol and it says do not wash in soap and water, on the instructions inside it says STEP 3 FLUSH THE FILTER OUT WITH WARM WATER FROM THE CLEAN SIDE OF THE FOAM TO THE DIRTY SIDE, a contradiction. having not put the viper on myself i need an idiots guide to the above and dismantle/clean pls
