My Car Was Running Like Shit With A Pod Filter On It.

Ok so i recently installed a DRIFT brand urethane pod filter to my RB25DE, Completly stock engine. And the performance drastically reduced, There was SFA backpressure when driving, And it was just really doughy and had shithouse throttle response. When i put the stock airbox back on it went back to normal. I had it installed properly with the AFM plug correctly on and everything was correct. Does anyone know why this had happened? and will i be better off leaving the airbox and putting a k&n panel filter in or something, Or figuring out a way to run a custom CAI into the top of the stock airbox with the K&N panel filter.

Any suggestions that people have that can improove the flow and maybe power with CAI setups please dont hold back im open to anything, Even if you have had a decent pod setup.

p.s

The pod filter was bracketed to the chassis of the car so it wasnt defectable, With no heat sheild or box to cover it. It still ran like shit regardless of the engine bay temp though.

Maybe if you run the pod down through the holes that the Turbo model intercooler pipes are meant to be so its got cold air from outside the car but i dont know if you can be stickered for it.

some filters use an oil to help filtration which affects the afm in some cases.

maybe you bumped the afm during installation?

just give the afm a quick clean and see how it goes.

possible... but that desnt explain why it ran fine again when he put the stock box back on though. I still think the air filter is of shit quality

lol... make sure its not one that says "Not recommended for turbo charged vehicles" on the bottom of the packaging

Get an Apexi Dual Air Filter Cone it runs good for me

lol i cant afford that :D

That drift piece of shit was $54 for the pod and adapter :P

i cant see any problem really with poor filter design, since it should be able to run without a filter at all with no problems.

my take on it is:

- oil used on filter.

- heat soak from engine causing high temps in the intake.

that said, it's been proven that a pod filter does SFA. the turbo guys are running 200+rwkw with the standard airbox with a decent panel filter.

if you really want to run a pod filter, then a custom air intake with a heat shield is a necessity.

I dont see how though, Ive seen this exact pod filter on many turbo cars and a few N/A cars and it ran fine with no problems...

Yea just get a K'N panel filter inside your stock airbox so it's nice and stealth, I wish I did that, I've got no idea where my stock airbox has gone now. So i'll be running my boxed PoD with the factory snorkel shooting air in for now.

I just got a k'n pod filter and it wouldn't fit into my stock box but i left the intake bit of the stockbox in place so it flows some air towards the filter and so far no problems, no noticeable decrease in power or nothing. I will be getting some heat shielding to "box" it in as such and using the stock air intake then i will have cold airflow going to it. Only problem i see is with my car R34 GTT there seems to be alot of hot air flow upwards towards the pod filter where as the other side of the car doesn't get that much hence why it needs to be "boxed in" and also so that it is legal.

Does this help?

http://www.twinturbo.net/ttnetfaq/FAQpages/stall.html

It seems alot of the 300zx guys out there had problems with pod filters. Basically the link explains that by putting a thinnish strip of duct tape on one side of the pod it disrupts the air flow allowing the AFM to get a better reading. Try this first and see if it makes a difference.

Hope this helps!

Put the filter back on.

Chuck a slightly damp chamois over the filter (Not dripping wet, ring it out properly first!)

Now blip the throttle to some high revs.

Does the chamois get "sucked in"? no? Shit filter.

Yes? Problem isn't from it not flowing.

      Yet another RB Neo misfiring thread after reading all the others.

      Good tips, will get on those tomorrow. When doing the maintenance I did move a few of those connectors around, and things that are old tend to not like moving around. (Like me).

      Don't try it. It will be shit. Better chance of damaging the engine than gaining any knowledge about the old one. Maybe, but unlikely, especially if the O2 sensor is working. You can use NissDataScan to look at the stock ECU.   Cleaning the AFM is seldom necessary and seldom helps. The R35 coil & loom conversion should eliminate dud coils or plugs. But as you still have misses - look to the plug where the coil loom connects to the engine loom, and the CAS plug. Need quality connections there. Also look to injector plugs. And the AFM plug while you're at it. Also look to whether your injectors are clean and flowing evenly. Get them out and onto a testbench.

      Good to know, I feel like I am in for a rollercoaster ride that looks like a sine wave.

      Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?
