2006 Gt Air Induction - Advice Please

[Makina]

I'm looking at fitting an Air Induction to my 2006 Celica GT.

Found this on e-bay http://cgi.ebay.co.uk/K-N-Typhoon-Induction-Kit-Toyota-Celica-1-8-192PS-00-06_W0QQitemZ150401391153QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item23049f1a31

Does it sound about the right price and will it make much difference?

Also found this and it's much cheaper http://cgi.ebay.co.uk/TOYOTA-CELICA-1-8i-00-05-AIR-INDUCTION-FILTER-KIT-S-R_W0QQitemZ160383170323QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item255794f713

so which is best

There's a lot of talk about these over on Celica club. They are notoriously awkward on the 190 engine due to the mass air flow meter readings being knocked out. So perhaps have a check over there to see which ones actually work. Most require modification to get a correct air flow reading otherwise you get the check engine light up.
