i know there are tons of threads about filters, but none on what exactly is the dead spot

is there a dead spot with the factory filter or is it just an after market thing

and what does the dead spot do, any information would be good

I have a K&N pod filter and suffer from deadspotitis.

Basically when I use to put my foot down with the stock filter, there was torque steer a plenty, and sustained wheel spin out from the hole, but then power started to die off around 5000RPM.

With the pod, I put my foot down and theres a noticable lack of torque down low, limited to no torque steer, but above 4500 things start to really move with a bit of torque steer and sometimes will break traction as the power comes on.

Nobody as far as I know can offer a solution. Barry has his metal spacer rings which are said to improve things (I don't use them), however I reckon they would also an offer an improvement on stock as well, and while making things a bit better do not actually solve the problem.

Some people suffer from this and some don't. I don't think pods or my CAI induction setup are inferior, I think I'm just unlucky. I'll be moving back to the standard filter and airbox when I get time to put it back in.

That said, are there any real gains from the K&N panel?

well sum say yes and sum say no. there was a thread by TZABOY who did a dyno with and without airfilter and CAI and there was no gain or loss. but to my when i installed my K&N panal filter i did not notice ne dead spot or flat spot but did realise the car was more responsive under heavy throttle and car was alot rev happy. its all to there own basically. sum say i gain and sum say i loose or still the same.

Yeah what I forgot to say that with stock filter you could fill the power drop off after 5000RPM. With a pod it didn't drop off as much. Like Ashneel said, it was a lot more happy to rev.

For $180 or so, it's a worthwhile buy. If it doesn't work out, its only $180 and you could probably sell it on.

provided that they didnt read your post.............. :badgrin:

I always maintain with the stock filters - if they are good enough to flow 180Kw (on the ralliart), then they surely should be OK for a 160kw-ish engine.

Mitsubishi uses the same filters in the Ralliarts as they do the executives. If changing the filter gained them some worthwhile power, wouldn't they have done it? (to save on some other changes - eg. extractors etc.)

The K&N filters do actually let in a bit of dirt over factory - I tested this on my old car - with some white sticker paper - there was dirt let through with the K&N, but none with the factory filter. Dirt is an abrasive, and it mixes with your engine oil. Your engine oil runs through your bearings. Think about it.... :doubt:
