I'm unsure which Aitec one to get. Do I go for the large one with fans on the front (not sure if single or twin pass). Or do I go for the slightly smaller one (single pass) with its fans behind it and a side deflector plate to allow air past the intercooler onto the radiator ?

What are the differences between single or twin pass?

The thing is , I like the look of the large one. But with fans at the front does this reduce air flow. If so, can the fans be placed at the rear. Or do I go for the slightly smaller one ?

Any help would be great.

Thanks.

Gaz.
