Sorry, I couldn't see any support bracket.

I'd also like to see it extend a little farther at least to the center of the grille.

Is that where the high pressure air can be found? With the bumper partially blocking the front, how much pressure (absolute or relative) do you think you can find? Otherwise, anything we can dream up here is no better than the stock airbox, located in front of the radiator support and drawing air from the underside of the hood. I read something about how to locate the higherpressure areas on autospeeed.com, using a DIY pressure switch setup (http://autospeed.drive.com.au/cms/A_2081/article.html)

If the latter is true, you'd be better off cutting the hood to install an NACA-style air scoop near the forward lip, and sealing it to a similar hole in the stock airbox.

The alternative would be to measure the air pressure in different areas around and in front of the radiator ( anywhere else?) to find the best place for an intake- probably where the stock airbox was. And possibly adding a little more pressure with either an air dam, spook spoiler, et al, (best idea IMO, but modifies the look of the nose), or an air scoop/funnel of some kind under the hood behind the bumper (block air to the radiator) to increase air pressure.

You'd have to put together a pressure measuring device, and measure the air pressure in areas in front of the radiator while the car is moving. I don't know of any device like that; like something that plugs into a VOM, so you can take reading while driving.

Put the airbox back together! You must have had too much time on your hands when you came up with that one.

I know a couple guys that wil take the top off the air box for autocrossing, claiming it should let the air in easier.

I have a cone filter with a 3 inch aluminum tube off eBay. How can you stretch the rubber air tube over the metal tube. Hot water?

thx

I don't want to hyjack this thread, but I have a kinda stupid question about the K & N filters? Why can you use these and not worry about rain or water when you would with a normal air filter?

Also, once you wash the K&N does it need to be re-coated with an oil? I was told this is something you would want to do.

I got lucky, a spare engine I bought came with a K & N filter. It was an upgrade I wanted, but at the time didn't have the cash for. :laugh:

K&N filters do need to be cleaned and re-oiled. They sell a kit of supplies to do this.

Maybe it's only paper filters that you need to worry about getting wet?

FWIW, I don't worry about my K&N filter getting wet, but then again its inside the stock housing.

Oil repels water, and what little might make it through isn't going to harm anything. That said, I would still prefer to have some sort of shield deflecting the majority of rain that might be encountered while in driving in a severe downpour.

A lot of time and maybe a few fingernails will get it. I had to work mine for a long time before I could get it on. I haven't removed it since. I just worked the rubber with my hands and just did my best to try and strech it.

I'm still looking for a 70 mm tube since that's the size of the of the rubber duct. That's about 2 3/4". It would be easier to put a 3" filter over a 70mm tube than it is to put a 3" tube in a 70mm duct. Or better yet, find a filter that fits the 70mm tube. K&N makes them in all sizes.

Since I only have an elbow ( about 7 in radius) do you think a muffler shop could shrink the end a little? It would only need to be about 1/8 in on the radius. How far in does the shrinking have to tool go in? You only need about an inch to get the tube on.

thx

Now that I got my intake tube on, I'm trying to figure out if it's any different or better..

Assuming that the aluminum tube & the rubber connector are doing their best, I'm wondering if the 'cone' filter is good enough to really allow air to flow better. It's a kind of a cheap filter with a red filter element, the base is chromed and on the narrow end is a chromed plate with a hole in the center, and a smaller innie-cone in there.

The reason I'm wondering is that I took the fiilter off and the engine RPM went up, so I concluded the filter was 'restrictive.' I proved it to myself by putting my fingers over the open tube, and the engine RPM dropped accordingly.

Should I switch to a (better) K&N type cone filter? Should there be a 'performance' difference in the length or taper of the cone?

thx
