Thread: k&N drycharger, is it worth it?

I was reading up a little bit about the k&n drycharger cover that goes over the filter it supposedly can stop water from reaching the filter (or reduce it at least) anyone have one on their k&n? Im building a custom cold air intake keeping the battery in the stock location for under $100 (once its completed i will post a how to), I would just get the aem bypass valve but it wont fit the 4"od pipe im using, I live in south florida and drive somewhere near 50,000 miles a year and dont want to take any chances in the rain. Im planning on making a plastic panel that sits behind the foglight to hopefully stop any splashing, any other ideas of keeping the engine safe from water would be helpful and appreciated.
While were on the subject what does anyone think about the foam filter wraps sold by k&n that filter 90% of the dirt and only reduce airflow by 2%, is it just k&n trying to make people buy more stuff from them or is it a good buy.

Check for dirt where you will install the K&N, I know people using this setup for years but they do make sure the wheelwell plastic stuff is in place and that kind of things.

As for the dirt, that might give a hint where the water is going. I wouldn't worry too much about it, some drops won't hurt and for water to go all the way up in large amounts I guess the filter would be needed (partly) submerged for that

I'm sure that foam filter wrap only stopps 2% when its clean and not a spec of dirt, let it accumulate some **** and I'm sure it won't be so efficent

pantyhose works good too

But will pantyhose keep the water off of the filter if it gets splashed, that's the main thing I want to acomplish keep water from entering the cai

I didn't want to get into this because I know it's not your plan but I would re-think the entire idea. Find a way to mount the filter up high by the battery. Then build a shroud or box around the filter (and possibly battery) that seals again the hood. Leave the box open at the bottom so it can draw air from under the battery through the hole that goes to the front fender area.
This way you have no worries about water, you don't have to buy some crazy filter, by-pass valve, or filter cover. You will need some lunch trays, weather stripping, sealant, and ingenuity. No big deal.

That might be the easiest thing yet I did something like that on my 1.6l to keep the battery out of the heat(no space in trunk with amps and such), best of all I won't need any lunch trays because I have this really heavy duty corugated plastic stuff from when walmart redid their shelving (its amazing what you can find in walmart dumpsters), I might be able to use the old weather stripping from around my doors, I might just have to rear mount the battery do you think 4ga wire would be thick enough I have plenty of that

I used 4ga wire when I rear mounted my battery and it has worked well for me over the years. Others insist on thicker wire. I've had no trouble.

Try splashing water on a stretched panty hose, it will catch it. I'm also planning a CAI and still working on how to cut the chassis in a decent way. Also going for the clean engine bay so probably no lunch trays for me but Ben's idea is good, absolutely safe and guaranteed hours of hobbying-fun

I don't know if you have a harbor freight tools or if they even deliver there but I just got a hole saw set I think it was $11.99 (the kind that fits into a power drill) and attached a piece of plywood to the bottom of the sheet metal where the resonator box used to be (mine was gone when I bought the car), the plywood kept the hole saw right where I wanted it to be, sprayed some wd40 to lubricate the bit and drilled a 4"hole, and then lined the hole with old door weather stripping fits perfectly, the only thing was I had to move the battery tray over 1/2" by just drilling new holes over farther. I may do a hybrid setup if there's room, I might have to turn the battery but thats easy, a cold air that goes behind the bumper for non-hurricane season and an "isolation box" like ben said for the hurricane season depends on how much room/time I have this weekend
