KTEC Panel filter for Clio 200T

Hi guys, after honest opinions please.

KTEC claim an 8bhp increase by using their panel filter in the 200T, not that I'm disputing this, however would welcome any owner reviews who have this fitted and opinions on whether this is actually a necessary mod, especially now that mine is running 245bhp. Would I need the map adjusted in any way or will the car work out that it can breath better by itself?

What worries me is that I've heard the oil that you use to treat the filter can somehow bugger things up in time with the car although I'm sure that's not the case.

Cheers guys,...
 
I have had the filter in mine since day one. Prob just an increase in induction noise to be honest
