Can anyone tell me the difference between the 2? I understand that one lets in more air than the other, but is their any other differences. could I accomplish the same thing by removing the stock cover and running it that way (not that I would want to), or is there more involved? I am just trying to understand to hole picture not just the fact that you get more air.

 

Doesnt it space it away from the engine so you can get cooler air.

 

Not sure, that is what I am looking for, any differences that is there, But good question.

 

More air flows through the filter element. Period. Taking the cover off your stock one will still leave a restrictive filter in place.

No shortcuts. LOL Either get a higher flowing element, or leave it alone.

 

So what your saying is that all you would need is a high flow filter not necessarily the entire kit?

there are always shortcuts, some work, some don't but if you understand the concept and have the materials anything can be done. that is how the makers do it. fab it and see if it works. (not saying by any means that you don't understand it) I just don't see spending $200-$400 if it is something I can do at home for $50.

 

If you can locate a free flowing element that fit your backing plate, you would indeed benefit from it.

 

Buy the largest and best element you can afford, as we have witnessed evidence with Ness & HD Stage I set-ups, even holding 80" Evo's back, while testing on our dyno.

Would an Arlen Ness big sucker stage 1 or 2 be best for a 107 M8 with a FP3 tuner and 4" RCX with no baffles? I want to provide the right amount of air but not overdue the air or my wallet. Thanks

 

 

What about cutting out the cat and then running baffles? i really want the cat out.
