panel vs cone

[dan_b]

Ok. I've said it before, I'm not doing any more mods.

But, I reckon I need to replace my air filter anyway, so, the question is:

K&N Panel filter, or K&N Cone?

My car:
3B, MTM chip tuned to approx 280BHP, with Scorpion de-catted exhaust.

Should I get the panel filter, or will the cone give me much extra?
What heat-shielding solutions would be advised/required for the cone?

Votes and comments please!

Skip the K&N:s. Either run with the stock air filter (you could possibly modify the box for better flow) or get yourself a "dry" cone filter (like the A'PEXi Power Intake). The oil used in the K&N:s can destroy your MAF. If you go for a cone, make sure you shield it properly and route cold air to it.

Just my .02.

You could go for a direct panel replacement from ITG.

The standard panel filters are oiled but it says they never need cleaning and re-oiling. I thought the problems occured with k&N when they were re-oiled after cleaning and you used too much.

K&N is fine from the box - never had any probs with it - just if you have to clean it dry it properly and don't soak it too much in the oil.

Which ones are suitable from ITG, they don't list the S2 as an application. I know ITG are respected, a frieind of mine got an ITG kit on his Elise, make a huge difference for him.

Can't say for sure but the closest match they seem to do for the 3B is:

WB-361

The filter is the same as most VAG 1.6 diesel engines from the eighties and early nineties. ITG have the same part number for two different VAG filters though so it may not be a perfect fit.

ABY filter is the same as a MkII golf Gti etc. ITG part no. WB-481

I've seen lots of adverts for cones with a 3" feed pipe diameter - will these fit? What's the diameter of the MAF pipe, it's 80mm or something like that isn't it? A 3" pipe should just squeeze on to that?

Cone Filter

Hi!

Yes the MAF dia is 80mm and the 3" filter will fit, however you should not mount a filter directly on the MAF because it can affect the reading.

It´s a better idea to use some sort of pipe between MAF and filter to straighten the airflow. It dosen´t have to be long, some filters have a short rubber neck and that can be enough for some applications, but a 4-5 inch pipe will do a better job in some cases.

It's not an 3B, but according to Autospeed's article Eliminating Negative Boost,
the pressure loss over the stock panel filter in the AAN is almost negligible.

It's the other components in the intake system that make up for most of the pressure drop.

This looks useful?

I've also heard (from Sal) that the Dahlback induction kit does the business very well. After some hot runs he was able to feel much cooler temperatures on the air filter side of the heat-shield. The kit is expensive, but he said it bolts on a treat...


PS - Sal's car is an ABY if it makes a difference - dunno if induction kit for 3B is same - I suspect it would be !

im using a 57i from a s13 200sx at the moment had it in the stock room and it fitted nicly and sucks like a dyson!
not loud enough yet so i think a turbosmart wastegate vented to atmosphere is needed!

I was impressed by Sal's MTM setup . After a long tuning run on the weekend it was cold on the air filter side of the heatshield. Very effective. Not worth the money but simple to replicate with 2 3" 90 degree bends welded together.

Lee,

I think that was a Dahlback cone set up.
