Congratulations.

You now have a filter that actually filters better, is cheaper to replace, and fits properly.

I had it in the correct way. I checked many times... I just couldn't get it to close

The solution is a 45 Degree Silicone coupler ....

I recently added a 90 degree elbow (from spectre) to the funnel because I was afraid that it might touch the clam when on high rpm. Sorry, no pic because I did it at around 1AM and didn't bother to take a picture. The clearance is good but sound has been dampened. I'm looking for other ways for the funnel to have better clearance from the clam. Is there anybody here with a good suggestion?

Replacing the air filter is a PITA. I miss my old Chevy with the wingnut clamped circular filter.

Like someone self mentioned, the worst part was getting the box to line up and then get the clamps on. I used a big pair of channel locks to do it after making sure the box was lined up.

I appreciate the thread a great deal.

I pulled the snorkel off to make it easier to change the filter. When I went to install the plastic screw at the top of the snorkel assembly, it would not thread back in. The screw just fell into the hole. I got a look at the hole and there is no fastener for the screw to screw into....just a hole. Either the fastener fell into the air box when I took the screw out or it was one of those expandable fasteners that fits into the hole before the screw (like the ones that hold the wheel well liner in place) and somehow I lost it when I removed the screw.
Anybody know what the hell holds the screw in place?????

Thanks,

I believe its a screw rivit like the ones holding your fender liner in place.. maybe the base fell..

It is an expanding fastener. It is slightly different from the wheel well liner fasteners in that the tips are attached to each other and it is narrower.

RoadDad · 09-07-2008, 07:22 PM

The base looks like this (but has a screw instead of this push type):

You can look in the air box but it couldn't fall through the hole on top that holds the snorkel on. The fastener is too big. I'd look all around the floor before popping the air box open again.

VINSTA · 09-08-2008, 08:09 AM

Thanks all for the help. Makes me feel more confident that the fastener did not go into the air box. I'll keep looking around for it.

Thanks again!

which still amazes me how Ritchie was able to take my old green filter out and put the new one in all within 5-10 seconds!

all he did was remove the wheel liner, swap out the filters and close the box. And it closed properly...

I did a filter swap without taking the wheel off..

did it once, and never could do it again..

Tim,
If you are saying that the stock filter does a better job than the K & N, I might have to agree with you.
I have run two K&N's for a total of about 6000 miles. During that time, two Blackstone oil samples checks produced Silicon levels in the oil of about 30 PPM. The universal average is 9. Blackstone indicates the oil I use typically has about 12 PPM of Silicon so if I subtract that from 30, I get a true sample of 18. This is twice the universal average. Silicon can come from a number of sources, but a common one is dirt in the air. I looked at the K&N filters carefully and noticed that in some areas, the engine side of the rubber sealing surface has fine sand-like particles attached to it. These particles also show up slightly beyond the sealing surface on the engine side of the filter. Though I can't say for sure, it gives the appearance that the relatively incompressible rubber sealing surface does not contact the mating air box surface 100%. In other words, it looks like a leak.
The stock filter is soft and compressible at the sealing surface and might do a better job of preventing leaks.
I just switched back to the stock filter.
Any thoughts from other K&N users?

Any interest in re-running your test to see the result after switching back to a stock filter?

ericwgexige · 10-09-2008, 11:50 AM

Why do you need to remove the wheel liner? I just reached in from the top of the engine bay, unhooked the 2 clips, swapped filters, lined up the 2 airbox halves properly, and snapped the 2 clips back on. Viola! Sounds awesome on 2nd cam!

PT17FLYER · 10-13-2008, 06:43 AM

Finally got to experience the "joy" of changing the airfilter last Saturday. Spent about 20 minutes trying to get the airbox to close

Then all of a sudden...tadahh!!!

Still don't have clue what I did different.

goelise · 10-14-2008, 03:38 PM

i just cleaned my air filter out and closed it, again, in just a few seconds...not meaning to rub it in but really, its quite easy.

Isn't this improper jack stand placement?

Is there a place to put a jack stand in the rear without removing the aluminum panel?
