Sik!
Ive actually done a similar idea...
I used to own a VT LS1 powered commodore and I upgraded my intake pipe, so the stock one now is on my skyline!
Same place - but I didnt even think of using the funnel as the entry at front bar - Thats what Im gonna do on my lunch break, go to bunnings! hahah
This is the airbox I made last weekend, so with the cold air pipe and this, it *should* work ok! haha
