Has had very good reviews in Japan. Much better than a K&N just because of the fact it is a dry filter. No more cleaning with petrol or oiling filters.
I am selling this because I have abondoned a EFI upgrade on a car. Was going to install a MegaSquirt in an Alfa. So I no longer need it.
It is as brand new condition and comes with the original box. It still has both mounting gaskets.
These are worth $150 new from memory. I will let it go for $100.
The internal diameter of the flange is 85mm (8.5cm), by internal diameter I mean the size of the hole the air flows through . This is a filter element only I have for sale, it does not come with adapters or tubing.
BTW the box is made out of an old plastic airbox from Renault 21. I can chuck it in for free if you like, it will just hit the bin otherwise. It is a good heatshield and can be ducted for a CAI.
