cold air intake issues

[skyy_4life]

it did have a k&n filter in it, but still ran fine,
and its in the engine but by the core support, now please tell me how every other cold air intake brings in air because they ARE still in the bay.... smart ass.

ANYWAY; back to what i was saying,
i beleive its the smaller opening on my adapter, but due to work and many other things i have not got around to installing my other 90mm adapter.

or because small droplets of oil from the oiled filter have landed on the maf sensor blocking its ability to sense airflow

Pure theory man, i'm not an expert on maf's but basically (if i understand correctly) it is a hot wire that measures air based on how quickly or slowly the air cools it (the higher the velocity of the air coming in the faster it cools), which is converted into a fairly accurate measurement of the amount of air coming into the engine. I'm not buying that a very light mist of oil (if any at all) is going to affect the cooling of the maf sensor (mainly b/c i have run a K&N for 5 years now and not had one problem and i have re-oiled the thing 3 times now). I believe that someone assumed that the reason their engine was running rough after a cai was because of the oiled filter getting oil on the maf and then everyone went with it. To the original post sorry for being a thread jacker, but i just figured i would state my opinion since this dude felt the need to state his.

i have had many a k&n owner bring his car into my shop with all kinds of symptoms. after going through the usual suspects of diagnosis we usually end up finding out that the owner had recently cleaned and re-oiled his filter. a quick shot of mass air flow cleaner and symptoms go away.........pure experience man but we normally diagnose it on obdII vehicles by reading the live-data stream with the scanner and compare the maf readings at idle vs what the spec says on alldata. its not super common but i've seen it 4 or 5 times, the first few we replaced the maf sensor before we tried cleaning it. the only times i've seen where a symptom was relieved by cleaning the maf was on cars with oiled filters, its cheap enough, and easy enough to rule out early

haha well all of your experience still proves nothing to me. like i said i have run one for 5 years and not had a single problem.

Wow..one person with no problems. Want a gold star?

Fact is, the oil can and will disrupt the readings. Most people use too much oil, and then the MAF gets covered in a film of oil. I've had this happen to two of friends vehicles who foolishly installed a K&N, both of which had problems that were remedied by cleaning the MAF of it's oil slick.

To the OP:
Nice try, but the factory intake pulls air from behind the bumper, outside of the engine compartment. The air there will be cooler than where your current cone filter is sitting.

Clean your MAF and change out the adapter.

so your telling me with the cone facing the core support, were the air box is on an OBD2 truck (right were the cold air intake is on a stock truck) its going to do any different?



Lets be serious.

Yep, Put a Spectre filter on mine. Had the same thing. But I knew about the dirty MAF and gave it a cleaning. Also Wheeling, the dang tube kept falling apart and it wouldn't run at all. Was coming apart at he fancy cheap plastic crappy clamp that came with it. Some 3" Radiator hose and two clamps replaced the clamp and it works fine. I didn't add the tube and all to be a cold air intake, because now the filter is sucking air from engine bay. I added it so my filter sits behind the coolant resorvior, which acts as a water and mud damn when I submerge the truck. As the factory sucker spot was behind the headlight, great for a non wet terrain traversing truck.
Oh and on the cold air thing and theory, How about all those 60-70s muscle cars with the chrome breathers under the hood? They hauled ass sucking engine bay heat. Unless someone's icing the intake (which drag racers do) before a run down the drag strip to cool air flow or running it through some type of ice cooler, the slight difference in outside engine bay and inside engine bay temp probably ain't making that much difference in the cold air's denser and burns hotter theory!

yeah... i think i do want a gold star

I know this is over 10 years old, but just ran into the same issue working on my buddies truck, not sure of the CIA you were using but I ran into a simular issue. The issue I seen was that the MAF was backwards and when I corrected the orientation on the pipe the issue stopped
