K&N air charger kit - OBD code issues

[Bob Ayers]

does they same thing go for 93's? i mean would putting in a kit be worthless and not add hp?

Absolutely correct! All you will get is more noise, and a lighter wallet!

The biggest insult is how much it costs...

When I put mine on I noticed a difference on the take off. It definitely made it breath a lot better than that RESTRICTED air box. Did you make sure all the hose clamps are tight on yours. Like seabiscuit said can you get any pics of this kit?

I will snap some pics of it this weekend.

You could
use a sewer pipe for an intake, and you wouldn't get any more air flow than the OEM!

The K&N kit disrupts the airflow across the MAF sensor, causing inaccuracy in measuring actual airflow. The ONLY advantage to the K&N kit is a lighter wallet! Install the OEM intake/air filter, reset the PCM, and you won't have any more trouble!

The newer style MAF's do not respond to CAI as well as the older ones would. It will really mess up a newer system and will result in the engine running lean and burning itself up. The only real way around it is custom programming to put more fuel to it and even things out. Right now the engine is literally getting more air than it knows what to do with.

I recently installed a K&N air charger kit on my 2006 3.0 V6 Ranger. I keep getting a Check Engine Light with codes 171 and 174 indicating that both O2 sensors are reading a lean mixture. I erase the codes, and the light kicks on again after a couple hours of driving. Have any of you guys experienced anything similar? I had a K&N air charger kit on a 2001 Ranger and never had this issue; for some reason my '06 Ranger just doesnt like this kit!

Another thing I just thought of is newer trucks have a capacitor to save the settings if the battery goes out, so simply unhooking the battery won't wipe out how your truck has learned to run over the past two years. You have to unhook the battery and turn the headlights on, the capacitor will go down almost right away, then just rehook the battery back up and try it again.

The engine is getting exactly the same amount of air, what's causing the lean condition is the MAF sensor is telling the PCM there is a lot less air flowing, causing it to reduce the fuel!

All PCM's have the capacitor on the unswitched 12V for the KAM!

That process usually does the trick for a CAI install on a newer rig that has the capacitor.


Any way you cut it, right now (or back when he posted) his computer was/is royally confused.

You missed my point! I was trying to say ALL vehicles that have a PCM have the internal capacitor, not just the newer vehicles.

I had the same problem, with the same codes, though at the time the spark plugs were in desperate need of being replaced having gone 88,000 miles. After taking it in to the shop, the mechanic told me that the truck had the flex fuel plugs in it, which she said wasn't the right ones for it, and that instead it was supposed to have the motor craft nickel plugs (SP 413). So I changed out the plugs with the ones she told me and the light hasn't come on since. So try doing that and see if it clears it.

Why do people think putting an air filter that sucks hot air from the engine compartment is a cold air intake!? The stock intake is actually a cold air intake... kn filters are not.

Because it is marketed as a "Cold air intake" and people are stupid.

So true... I got into an argument with a buddy who had one on his civic. Hes all like this shinny aluminum pipe makes the air colder! or some bullshit... lmfao
