Wasn't looking for an alternative for everyone to do... just for myself ;-) I personally don't see the air being "cooler" just because it comes from the front of the air port... I'd venture quantity not angle being the main concern at the point I'm at... if angle is a concern, why not shoot the intake straight off the intake manifold? I don't doubt the philosophy of it, just thinking more air is better than what was prior set up... I honestly just don't want to pull the box, cut a hole, order a part... my mod is simply for myself... not trying to convince others mine is better... just don't feel like ordering a part when I can simply pull off the lid

I see the braces in the lid that help keep the filter locked in... I just used a c-clamp against the filter and it's not going anywhere ;-)
Looking at the ISR mod as well... I have a piece of blower tubing off a leaf vac that has similar dimensions and may work... also working on possibly getting a nipple installed to it to skip having to put a tee on another vacuum hose. That too is just my idea for a mod without going to a muffler shop and having someone press some metal tubing to put in place of the ISR...

Happy Mod'ing
