I'm a relatively new xfire owner, 07' limited areo blue 53k on motor. I've seen Syfi's DIY intake and I like it but was also wondering if I utilize my stock cover by removing the filters and doing (sort of) the ebay like set up will this still give me any gains? Essentially I'd like to try and fit 2 "smaller" cones right behind my grill and get fresher air. Has this been done before without to many problems or am I going to be taking on more than I can handle? I'm not very mod savvy so bear with me.
