I have an interesting theory on the whole intake CEL thing. the common code is a P0171 or P0174. Both i believe are lean codes. (i'm certain the P0174 is a lean code because i had it.) i noticed that shortly after I installed my CAI, I got a CEL. I checked it out and all looked good and i cleared the code. 3 days later, the code came back again! so i do a little further investigation. I take the filter off the intake tube and notice that the MAF has a little bit of moisture on it. then it hit me that it had rained the same day or the day before i got the codes. I dried the filter and MAF and then bought a K&N drycharger to prevent excess moisture from getting through the filter and to the MAF. Sure enough, 3 months and thousands of miles later, i no longer get a CAI related CEL.

So what i would like to know is of the groups of people that have aftermarket CAI's or the Airbox mod, how many of you have gotten the lean CEL. and if you have gotten the CEL, did you have a drycharger/hydroshield/or equivelent filter wrap on your filters.

Please only Vote if you have had a CAI/box mod for a considerable amount of time (i.e. longer than 2 moths or 3,000 miles)

 

can u please show me a pic of a drycharger and where i would be able to get it please.....i heard alot of people use these and no more codes

 

this is the K&N drycharger. you just stretch it over the filter and it covers it and prevents excess moisture from entering the filter. (THIS WILL NOT HELP YOU IF YOU SUBMERGE YOUR FILTER!!) http://www.knfilters.com/search/prod...Prod=RF-1035DK

 

thanks for the find, have any idea if they got 1 for fujita

 

I got the P0171 when I was completely stock so I highly doubt that is what is causing the CEL. Then again there could be multiple reasons the code is being thrown.

 

Yes they do, I have one on my Fujita. I can't remember the part number, but i'm pretty sure the one i linked you to will fit. the dimensions seem right.

 

No CEL ever for me. I don't have the full airbox mod but I do have the bottom open on the stock airbox and have had it that way for almost 20k miles. I have the XTC CAI btw.

 

I did the airbox mod and no cels. Did it the next day I pulled the car off the lot brand new and 3000 miles later no CEL.

 

I have a dry charger on my injen, and its great. However, my CEL stopped coming on with GM Stage 2

I only kept getting the lean code when i did not have the stage 2 once i got the stage 2 it went away and has not came back on in 3000 or a little over miles

 

i got the CEL a few days after i installed my Fujita CAI, and kept getting it every time after it rained, well a friend who acutally is on this site, recommended putting the drycharger and havnt thrown a CEL since, and i threw the drycharger on last year but i forget when

 

isn't this the same thing as the Injen Hydroshield?

 

K&N Typhoon, I put on the cover in the winter, off in the summer!
Had it for 8 months now, NEVER a CEL!

 

i dunno, my cel happens when its not raining, its only happened like 3 times, but they were on dry days. I have stage 2 and airbox mod

 

Never got one for my Injen.

 

the p0171 and 174 are not lean codes... i found that out when i got mine and researched... had something to do with the computer adding more than x amount of fuel or something. it's not a problem, can just be deleted, nothing is being harmed from that code.

 

Air box mod and no CEL yet waitin' for it to rear its ugly head. It's only been 3 months though.

Its a DD and survived the storms and humidity without a CEL.

 

my typhoon came with a drycharger, its been on for a week but no CEL yet, and ive driven through some NASTY puddles, (couldnt avoid them).
