Anyway to remove the filters via this route or only by removing the bumper? Just wondering for cleaning later on.

You will have to remove the bumper to change/clean/oil the filters, there's really no realistic way around that. After you've done it once though, removing that bumper is pretty easy. I bet next time I can do it in 10-15 minutes tops.

Basically taking off the bumper entails:

1) Remove that plastic shield under the engine (the same one you remove for oil changes)
2) Remove the little spoilers in front of the front wheels (sport package, 3 little bolts each)
3) Remove the little plastic cover between the radiator and the bumper under the hood (all plastic snaps)
4) Remove one plastic snap from inside each front wheel well, and loosen a bolt hidden under there
5) Remove two more bolts under the car in the front corners of the bumper (just behind the main front spoiler from the sport package)
6) Pull on the bumper near the headlights and it just unsnaps and comes free

That combined with the long cleaning interval on the K&N's should make it a non-issue.

Hmm... Some of those steps are extra. You dont need to do step one or two. Just need to remove the screws that are holding the bottom of the bumper to the black splash guard. Like 8 screws total.

At least that was my experience... I didnt go near the plastic shield.

now for some real airflow I thought I saw a pic of a white 370 with two small cutouts on teh bumper for the intakes to directly get air?? where did I see that?

Semtex you should bring your Z up to Fayetteville NC this weekend for the "Southern Invasion"!!! I'll have my Z out there with my new intake on it and Im getting kinda lonely being the only 370Z in the area. It's a couple hours drive I know, but it's a HUGE 2 day event with people coming down from New York and New Jersey area and as far south as Florida and Georgia! There is gonna be straight drag racing, street drag, and some import street car races, as well as a nice car show! Should be pretty awesome, I'll be out there both days.

Yeah, some of it did turn out to be extraneous. I pulled the bumper again last night to tweak things a little (had a minor vibration on the intakes around 7K RPM), here's a revised list:




1) Remove the front 6 bolts from the plastic shield under the engine (the same one you remove for oil changes)
2) Remove two more bolts under the car in the front corners of the bumper (just behind the main front spoiler from the sport package, same rough area as the first 6)
3) Remove the outer bolt from each of the little spoilers in front of the front wheels (sport package, 3 little bolts each)
4) Remove the plastic snaps along the top front edge of the bumper under the hood
5) Remove one plastic snap from inside each front wheel well, and loosen a bolt hidden under there (top corner of the bumper)
6) Pull on the bumper near the headlights and it just unsnaps and comes free

Semtex, when are you going to the 1/4 track to see how these mods do?

OhYeah

Is it much different with the noise?

Good post and work on you're part!

Youre number's are really impressive!
316.8whp & 248 ft/lbs (Dyno Dynamics) | 319whp & 256 ft/lbs (DynoJet) (04/23/10)

What type of real world gains are these in terms of launching, 0-60, 1/4 mile etc. Or can you actually feel the difference seat of your pants?

I'm really interested in doing something similar to my own car.
