New Air Filter

[bwmtnbiker]

Yes I know the stock Air Filter is the best up to 500hp.

My stock filter is about clogged up and I need to do something. I don't want to put a stock filter back in because it seems very restrictive. I have a few questions about what product to get. I know that making the pathway less restrictive and using a higher quality filter will allow the for a much greater air flow. The ability to draw air faster and smoother can never be a bad thing in my opinion.

That being said, what would be the best option. Im currently looking at Airaid kits because they have a $50 mail in rebate right now.

What is the difference between the two filter kits here:
Airaid Intake System 400-131-1
Airaid SynthaMax Dry Filter Intake System 401-131-1

Or would I see the same effects from using just the drop in filter?
Airaid OEM Drop-In Replacement Filter 860-341

I like them both, where did you get this info on the $50 mail in rebate. Are either of them washable?

You like both as in stock and a new kit or kit and drop in filter?

One of the XDP reps posted it yesterday. Here is a direct link

I'm sorry I like both of the intake kits you posted, I've been told not to go with the drop in filter if your looking for HP

I believe people on here have found that aftermarket intakes add up to 20hp over the stock intake. I believe the guys that tested this on the dyno feel that the stock filter was restrictive after 400hp I believe but what do I know lol. Just because the stock filter "can" support up to 500hp doesn't mean it's the best up to 500hp. I have the airaid and it's fantastic btw.

Im not to terribly concerned about HP numbers. Just looking to get a better flow because it makes things more efficient. I think some of the filters are cleanable.

I mean it makes sense. You increase air flow and what happens? More power or at least a quicker delivery of air. If you look at your turbo wheel, is it gunked up or look like its been sand blasted? Is there any dirt after the filter?

well said, depending on what I'm doing with the truck I use a stock setup or a Banks setup ( which I like the fit and finish).

Its all relative in what you want out of the truck. To me, I'd rather have the filtration and protection of the stock air filter, that is proven to 500RWHP. Multiple trucks have proven that number. Think about that power gain for a moment, its 20HP rather high on the RPM band, beyond what you will most likely see on a daily basis. You will see improvement in throttle response and spooling, but its at a cost.

If I was to select an aftermarket system for my truck, it would be the intake offered by S&B. Great numbers being seen on the dyno and track, and still offering good filtration.

I too am a fan of S&B. It is cheap, great looking, filters really good, and flows close to 40% more than stock at like 99% the filtering of the stock filter. The only real down side that I can tell is that it only holds about 10% of the dirt that the stock filter can hold so it has to be changed much more frequently (~once per year).

I ran both and while the S&B installed quick and was easy to clean, it was a PAIN because I had to pull it out and clean it about once a week during the winter months (dune season). I don't mind doing my maintenance on my truck, but that was quite ridiculous. I went back to the stock setup and now I pull my filter out to knock some dirt out of it at each oil change. I MAY go back to the S&B setup now that I'm running the MTW Stage 1 turbo...
