RXP / RXT air filter. Which one to use?

[RXPBeast]

I am installing a 4" custom air intake on my RXP and my RXT. What size or brand filter should I use? I was going to use the stock R&D pro flow power plenum filter for the RXP. I was thinking of getting a bigger filter to suck more air, but dont want the skis to run lean. I was trying to find the model number or one similar to the K&N filter that comes with the riva kit, as I see thats what greenhulk is running.... any suggestions?

PM Vman, or maybe he'll see this.... he's got a sweet 4" MONSTER air filter that lets so much air flow its rediculous then he ordered and outerWear for it. He did testing with shop vacs and leaf blowers and the whole 9 yards. Air flow was real good

Just search ebay for K&N filter. This is the one I used for my 4" intake. It is 9 inches long and does 1000cfm. I doubt Vman's was bigger than that. You can call outerwearsracing.com and tell them the dimensions and they will make you a water pre-filter for like 20 dollars. I used a 4" to 4" rubber coupler you get at home depot/lowes to connect it to the 4" tubing.

Outerwears has the pre-filter in stock for that K&N filter.

Don't think anyone would complain with 9 inches
girth is another story
