6637 filter mod question please
I have read about this mod, and saw a few pics of the install of the air-filter life indicator with the gromet, but here is the real question: What about the air-charge sensor? No where does it say where to re-mount this???? Anyone? Thanks as always

One of the reasons not much is said about it is because it really doesn't make much difference. Most folks do what Guzzle said. I just left mine lying on the fender liner under the filter.

ok, if this is a critical component of the air-flow as I was told when I thought I damaged it blowing out the airbox with compressed air, how can it just be "put aside" and still operate? Shouldn't it be in the airflow? Maybe wrapped in a plastic baggie at least.....?
By the way, this site is great...saved me a lot of aggravation....Id like to be a "supporter", how do I do so????

It still needs to be sending temp info. That's important, so it needs to be functioning. What's not so important is exactly where it reads the temp. As long as it's close to where the filter is, it's good enough.

Apples and oranges.
Apple: Potential physical damage to sensor - When you're blowing out your airbox with compressed air, the air flow exerts a lot of potential force on the sensor tip and can damage it.
Orange: Accuracy of temperature measurement - When the sensor is simply hanging under the hood as opposed to inside the filtered air flow, there is minimal actual temperature difference (2-3 degrees at most) when you're running down the road. If you sit at idle for a long time, you can begin to get a very noticeable temperature difference between ambient temperature and under hood temperature, but your filter is still pulling air primarily from under the hood and/or around the engine compartment when you're idling, so the comparison between under hood and outside air temps still makes not a lot of difference. Even if you have a completely enclosed airbox and are idling, the air flowing in will be heated up to at least some degree by the fact that the air box is enclosed under within the hotter engine compartment at a much lower than "travel speed" air flow. This has been measured and tested many times for verification by numerous people.
