Watching this thread for the 20+hp gain graphs.
Finished with the passenger side filter and I'm so glad the corner screw that's slightly buried isn't the PITA like the driver's side! I started the car and revved it to 7K......it must have at least 20 more HP!! Just kidding, I don't trust my butt dyno for supposed small HP increases. If my car is especially dirty and I wash and wax it, the drive after seems like the car is much faster to me, so I don't have any faith in that measurement. But I do have it on good authority that the cars with the snorkel do have at least 10 more HP than those that don't.........!! A late BMW mod to the induction system.
