Renntech with gruppe M air intakes is the best combo but will cost couple fingers

If you'll wait another 3-4 weeks Suncoast will have the new Ram Air hood and boxes for sale and I believe they will be less than anything out there. This is the only option that offers larger filters and allows more air from outside the engine compartment. It will be weather proof.

Is gruppe M same as the one on MHP website? Or is mhp a knock off? Looks the same, but way cheaper.
