Well i attempted to put them in while cutting corners and not taking the sway bar off, i don't know how some of you did it without that. The old ones come off fairly easy, just some hard spots to get the small hose off. Then while trying to put the new tubes in my friend dropped a hose clamp in the engine bay, it never came out the bottom, spent too long searching for that... gave up and put original tubes back.
but the K&N dropped in just fine! its probably my head but it does seem a little better down low with the filters.
