Even with a few of us running big bore 102/103mm high compression pistons with high lift cams, these filters still produce the goods. Marcel & myself have tested the +2mm bored throttle bodies & the stage 1 & 2 filters still offer great volume flow with great HP gains.

So there is no doubt in my mine they work.

Dino what are the gains in HP with your new XTZ filter & top plate?

Thanks
