i did this mod today. initial impressions:
1. its sooo quiet compared to my sri.
2. it *feels* like theres more torque.
3. taking another 30min in addition to the 30 min it takes to do this would do more. that includes making a bigger inlet hole, smoothing out the ridges inside the box, and possibly mating a bigger snorkel to the bigger inlet hole.
i have it lined up to the stock airbox with duct tape holding it on. i also cut off the resonation chamber on the snorkel.
i was bored, what can i say?
