Maybe sorry I may of read it wrong
Only slightly. Your photos have the velocity stacks already on the filters (so you can't see them) - I think this is the part Mick was struggling with.
Is that different to what monsterdorf has?
I think he has the velocity stacks and is fitting the filter's to them?
The stacks may be different ... but stacks to filters was the easy part for Jukie.
I just modded the air box to get the TPO ones on mine. Real simple. Same DP filter and lid.
The 4v setup is different to the 2v.
Perhaps you guys could post piccies of your setups as well for people to see the differences.
