I am ordering a replacement filter from ITG Filters and they need the dimensions of the air filter. Does anyone have the exact dimnesions? I suppose I could mail them a used filter, but doesn't seem very productive. I want the measurements to be exact.

 

Do you have a stock filter? Why not do your own measurements? It isn't hard, and you will have confidence in the reliability.

What is so special about ITG? They talk a good game, and the website has convincing looking powerpoint charts, and I love that they use terms like "whilst" and "in good stead".

But, what is so amazing about reticulated foam? There are plenty of those around. Amsoil has a two stage with different foams on the outer surface compared to the inner. I tested a K&M, a Uni, an Amsoil, and the flat panel OE paper one when i had my NSX, and found that all flowed adequatelty for the purpose intended, although the foam and K&N did provide a bit more air. The downside was they did not filter as well as the paper OE unit. ITG is pretty well restricted in that the closed-cell foams have to be large enough to flow air adequately, which reduces their filtering capability. There is no magical way to dance around that.

Foams do have a high capacity and do not deteriorate like the gauze filters when they are cleaned, so that is a ++. But ITG says they have 5X the service life? That would be 150,000 miles by my figuring. Hmmm........

Visteon has developed a 150K filtration system, but it is large, and designed to be mounted in an inaccessible place like the fender well during manaufacture. I do not see how a compact filter like the ITG can meet that capability. Nor does ITG have the engineering "depth" or deep pockets of Visteon.

The OE filter on the S2000 is more advanced than the NSX - it is an axial design similar to what the aftermarket provides, and provides more air than the engine can use by far. Unless you have a forced-induction modified engine, there is nothing really to gain except perhaps a few pinies at peak RPM - but are you willing to accept more dirt as a consequence?

I like AFE's filters if you are going the gauze route. They can also fabricate to spec, and someone just posted pictures of the AFE I recommended in a Comptech CAI used in a SC'd car - you might want to check out that thread.

If I had the numbers, I would surely provide them - but I thought you might want some additonal info before you comitted to buying the ITG. Not trying to be argumentative, just proving some thought-provoking info.

 

I had an ITG in my WRX and was quite impressed by the gain vs the stock filter. The ITG is quite impressive looking in person; they are the filter to have in rally circles, so I thought it would be good to try one out in the Honda, but they don't have one. I'll take a look at AFE and go from there.

 

Your title says "OIL" filter. Your post says "AIR" filter. Which is it?
And yes, if you have a car, why don't you just measure your own?

ITG doesn't have a filter to fit our car, they may have one that fits our car but they don't know what the dimensions are to verify, and if they don't, they can make one from very reasonably priced. I think they quoted me like $60.00 for the custom made filter...

I had a K&N in a previous car and an ITG and I just like the ITG products over K&N.
