So which one do you have gavs or are you still running stock (and what tune). I'm going to replace it for the heat dissipation and other gains anyway just wanted to see what fuel gains where out there as well (at least I can recoup some fuel funds to appease the treasurer). Tune will follow if not before as soon as the local guy is free. I didn't find the twintercooler.

I had a similar design in my liberty. The cross bar was right through the guts of the front inlet so it was basically two coolers. One above. One below and it just flowed through the bottom one and up to the top. Had massive gains over stock but that's not hard going from a top mount. I had upgraded the top mount first with good gains but the the front mount was another leap. And compared to my mates with a blitz one piece front mount and the same moods my lag was less and power up. But different cars react differently. Especially when the turbo was three times the size of the polos.
