If you do, provide direct-ingestion protection for bugs, birds, snow, ice, etc. A minimum of heavy screening or expanded metal.
The stock setup is turned so it makes the air follow a tortuous path and divest itself of these undesirables. Then, you are left with dirt & dust to deal with...the function of the air filter.

Also, the filter would become completely soaked in any kind of rain or when washing the vehicle. Shielding it completely from water, snow, etc would be very difficult as well. Putting the filter right behind the grill is a very bad idea IMHO.

Re: Intake air temperature

I don't disagree with all the statements, you have to consider the risks of running a tube to the grille, I put some bug screen in front of my intake tube and driving in the rain I've not seen any moisture on my air filter.

In the winter, I put the stock air tube back in because I want some heated air and I want to avoid snow getting sucked in.

Re: Intake air temperature

Running the filter to the grill or directly outside into the pouring rain will have ZERO negative effects on performance... if anything it will increase performance but you would not be able to use it due to conditions.

The only time water will be an issue for your induction system is if you completely submerge the filter into water leaving the engine with no option but to ingest water.

The small amount of Rain water you would get from a rain storm or by the rain water mist cloud created by an 18 wheeler on the highway would not hurt your engine in any way what so ever! Some people intentionally inject water into their engines.... Look up water injection.

Keep the filter above any deep water puddles and you will be fine.


SPEED SAFE, NICK

Yeah, water has a cooling and compression effect on engines, but it is not combustible or compressible -- so if it enters through the intake, it will tend to make an engine run richer since it is displacing air and not fuel.

Even if you doused your filter in water, and then put it in back in, the majority of the moisture will turn into vapor before it even hits the engine. It'll be the same as driving on a super humid day. As long as there is not a situation where a vacuum is created, you'll be fine.

Also, most airboxes have a drain on the bottom of them. Since this is not a forced air application, the pressure from the intake will most likely even be enough to suck in rain water...

Snow... Well, now that's a whole different story. I have heard of people with ram air setups getting their airboxes impacted with snow... I live in Florida.. So that issue is two scoops of 'not my problem'...

I know all about water and water/meth injection. Injecting water into a untuned motor will not increase performance at all in fact too much water will drastically decrease performance because water does not combust it inhibits combustion. Water injection, especially when combined with methanol, helps cool the cylinder charge (cooler cylinder temps allow for greater timing advance, greater exhaust cam retard and leaner A/F which all increase output) but allowing the filter to become completely soaked with water is still a very bad idea IMHO because it does not take that much water to hydrolock a motor. If you have a car in front or beside of you splash through a decent puddle that is all it would take to completely soak the filter and possibly hydrolock your motor. To each his own but I could never in good conscience recommend running a open filter behind the grill.

Re: Intake air temperature

So, to wrap it up, I took off the bwoody intake and put the stock intake back on with a K&N drop in. Don't know about HP, but I did see improved MPG on a road trip to Bristol this past weekend. I averaged @ 21.9 MPG, where before on a similar trip the best I could get was 17 or so. Totally unscientific, but on the surface, I'm getting better MPG with the K&N in the stock air box.

Ive posted this same thing in other thread...after hearing all the complaints about the performance drop after installing any CAI i decided to stay stock and just drop in a K&N filter...noticed the improvement immediately in throttle response and I now get 16mpg...I was getting 13mpg with stock filter...that K&N really lets her breath...the engine bay just gets entirely too hot for me to want to attempt the CAI

Do you think the engine is running too lean and will have long term wear issues?

Assuming it works in the same fashion as earlier PCMs, it will correct accordingly. The O2 sensors will do what they need to do to correct for 14.7 AFR.

These PCMs can correct up to a certain point...once that point is exceeded you then see changes in WOT AFR.

Re: Intake air temperature

For those of you who changed out your "CAI" and went back to a K&N drop in. Is the intake sound much quieter than with the CAI? I noticed a significant sound increase (good) when I changed out the factory box to my AEM CAI on my Magnum R/T

Re: Intake air temperature

It definitely is. It's the same as the stock filter.
