New Air filter

[Golf Houso]

Just to add my bit, I've found on modshack they claim a 28% restriction in the MAF grid ( mkV ) but I'm sure they are the same as yours. I pulled mine out and it ran as per usual, and a few other of us oilers have done the same. Car response coupled with a enclosed pod setup is definately better on the diesel, so should be very noticable on normal motors! The grid, according to modshack, is there to smooth the flow from the twisty turny stock airbox. Once a straight pod is added, no need for restrictive grids.

All the same, make sure you can put it back in if it wigs out!

Scan the diesel forums if you're interested, and keep modding!

Has anyone removed the MAF grid on a MK3, VR or 2.slow?
I've almost finished my Ghetto CAI w/heatsheild and any more noise would be welcome

Just a quick Q Aaron, do these housings just take your average run of the mill K&N pod filter inside? How are they fixed in there?

It comes with a filter which I haven't bothered pulling out, but I don't see any reason why a similar sized filter couldn't fit in there since you are supposed to be able to take it out to clean it.... something I haven't done yet

I will assume it would just be a standard 2.5" or 3" neck inside there.

Cool thanks Aaron, I got a 3" neck K&N pod on at the moment but am thinking of doing something like you've done but wanted to be sure the pod I have would fit in the canister. I assume the top or bottom of the canister comes off somehow?

Yep, screws round the outside of both ends.

Thanks for the info Aaron

how did it work out for you hawk?

7 months on and it's going great.

I haven't flooded the engine with water, even in serious rain, which I was a little concerned with, but I am a little aware of the intake hose's location, no driving through small lakes or flooded roadways, but in normal conditions it hasn't missed a beat.

I have pulled it apart and to clean/inspect the filter and it's all good (I forgot to measure it up for those interested in a K&N replacement), a few leaves and bits but really only a few, nothing like what I expected considering the suction this thing can provide at even half noise.

Speaking of noise. Yep, still love that aspect, You can't help but put the heater on full and drive with the windows down sometimes

On the K&N thing, I don't know that it would make any difference, I'm reasonably confident that the stock filter in these things has more than enough surface area and little enough restriction that it's not going to make any difference, so I'll be sticking with the oem part for the moment. One day, if I ever need to replace the filter I'll consider K&N, but like I said, I'm not convinced it would make a different in this case.


So in summary, for $169 I think it was a bargain, going from a dodgy pod to a decent pod to something which will not only pass a rego inspection, but also provides a steam of cold air is always a good thing.

I will add a BUT! While I don't have any sort of testing to back up my theory, I believe the biggest restriction will be in the MAF itself. A swiss cheesed airbox + K&N filter will go most of the way to doing what this setup does, so if thats what you have I wouldn't be rushing out to upgrade. Having said that, if you still have the stock box and filter, this isn't all that much more than the K&N filter alone so is well worth your cash and you get cold air goodness.

Nice write-up Hawk I should really put this on a higher priority in my list
