ive had two of them now, and agree they do look like original equipment.
there suppose to be 50% more efficiant, if thats true i dot know however i had a 5 bhp gain when i fitted mine and ran 17 psi through it for 2 years no problems befor i sold.
im running a pro alloy front mount cooler at the mo and thats a nice bit of kit however pricey at £400 or sumut like that and there not the easyest to fit and u have to trim your front panel so if your after ease of fit and original look the pace isnt a bad deal. the exchange is worth doing as that save you £50. shop around though to get teh good deals or get a 2nd hand one cheaper
