They are fine.

Got mine for

£125,

£30 for new clamps

£20 for backing plate, re-used standard fan with sensor unplugged.

£175 all in.

As for the clamps, they are fine on 90% of the hoses and pipes only 4 that need changing, and you can re-use the standard jubilee clips, which have never been bettered in my opinion.

You cant go wrong for that amount.

And as for proof of gains there has never been a independant back to back test, so its all speculation about which is better, just more of the people with high power run the more expensive ones, but even then most run charge coolers.

Obviously it wont be as effective as a charge cooler, but nor will any air to air heat exchanger.
