Actually your wrong again. The oval shaped I am referring to is the shape of the air cleaner the K&N unit. The same adapater goes across to every single Mitsubishi MAF sensor model ni the whole range. The section of the MAF unit which lets teh air pass through, is usually two square shaped units. Its the shape of the adapter going onto the MAF and teh air cleaner itself which is what matters.
Having fitted so many of these to so many different model Mitsubishi units from EVO, Magna, lancer, galant, FTO, 3000GT I see the same result time after time.
The shape of the MAF unit after the entry point of the air doesn't matter. It all comes down to the air being drawn into the air filter chamber and shaped and directed into the air flow meter.
When you see these kits it makes a lot more sense
The theory of this is correct but Pods do work on these units. But only the RIGHT type of pods. For many many years we (RPW) have been advocating the K&N Oval shaped pods which were origonally designed on the Mitsubishi 3000GT vehicles. These are not round, and the adapter is designed to actually funnel the air into the MAF unit, without disrupting the air flow characheristics. Basically because its oval shaped, it doesn't create a "Swirling Action" of the air and as such, the air is smoothed out and driven into the MAF Unit.
I lost count a long long long time ago of the number of customers who have fitted a "Universal" pod filter to the Mitsubishi MAF untis, and have them running badly, running rich or idling bad. They then fit the K&N Oval shaped unit, and it runs better and makes more power, without being in a restrictive air box.
I can say catagorically, that the unit we are marketing and sell (We sell at least 5 of these a week minimum) will definitly create more power and throttle response without ANY side effects.
Feel free to come and take me up on this as I garauntee it won't cause a problem
I'm running a Blitz Sonic Pod and I don't have any issues with boost or idle. But I will be doing some AFR testing with Silicon Angel with a standard box soon as we get some time (using Logworks3 and Evoscan). I'll be posing the results up on here soon. I'd like to try a few different pods in the future.
