I finally got my car running after about a month of sitting… Just finished tuning the idle speed via an old 80’s Actron timing tool. It was idling @ 1100 RPM after driving it into operating temperature. Its now idling at 730-750 RPM.
Anyway, since I’m a poor kid who works at CT, I wanted to do a ‘minor’ intake upgrade. I barely have any money right now for a full-on KA24E CAI, and I’m not really in the mood to use eBay just yet, so I thought about getting a pod filter.
I noticed that on one of my buddy’s cars, a 200SX (B14 Sentra 2-door), he installed a short-ram intake, buy kept the top of his air box under the hood, since there were two sensors going into it that kept giving him CELs whenever he disconnected them…
Anyway, I wanted to know:
How would I go about removing the air box and relocating/removing w/o CELing the sensors?
Whats the best way to install a pod filter on the KA24E MAF?
My description about the sensors (or whatever) are a bit bad, so I’ll post a pic of what I’m talking about:
The rubber hose going into it. It came off that little plastic square thing (what is it?). As for the sensor-thing, what is it for, and how can I bypass them w/o throwing a CEL?
the thing on the firewall that the rubber hose goes to is a useless piece of crap, just take the hose off and ignore it.
if you just take the air box out and put a filter on it you won’t throw any CELs and it will run fine as long as you leave the MAF there, you’ll have to get/make an adapter to fit a cone filter onto the end of the MAF.
to set off a CEL in these cars is pretty much impossible, don’t even worry about it.
Alright, sounds good… Any way to remove the sensor thing? Like just unplug it from the MAF? How about the exhaust hose thing? Won’t it cause exhaust fumes to inhabit the engine bay and get into the cabin if it were disconnected? What about that pipe and the actual plastic box-thing thats connected to the down pipe? WTF does it do?
take it right of from the manifold and and keep it in ur garage or w/e and no u need ur maf unless u wanna fuck around for another month trying to get ur car running again… leave the maf on there
if you disconnect that sensor it may throw a CEL as it did on my civic when i disconnected the sensor to put a short ram in. If your ghetto you can just leave the sensor hanging and zip tie it somewhere… if you want it to be proper you should drill a hole into your intake pipe and bolt it to there and seal the sensor with some silicone.
it doesn’t make a difference if you unplug that sensor or just leave it dangling, at least i haven’t noticed a difference if it’s unplugged.
the box on the firewall and the pipe from the exhaust can be removed completely, but you’ll have to find a way to block the hole in the exhaust, i’ve always just welded mine closed. you’ll still be able to pass an emissions test without it, it isn’t necessary.
if you just leave the box there and unplug it, it will keep the exhaust from escaping into the engine bay.
You can ziptie that sensor anywhere in the engine bay where it is exposed to ambient temperature. The farther away from heat, the better. I highly doubt it makes that much of a difference. I have mine tied to the back of my headlights.
If you’re interested, I have an Apexi cone filter (that you can simply bolt onto your stock intake pipe). It’s a great simple upgrade. I also have an Injen CAI extension as well (see sig).
Alright, sounds good… I’ll likely end up removing that ghey box thing and having the pipe welded shut… Which pipe am I getting welded shut anyway, the EGR pipe (from exhaust to intake mani) or the one that goes to the downpipe?
GTS - How much for the Apex’i cone filter? Any pics?
