A Forge 007p, Forge 008p or a brand new DV from the dealers (new revised part) would be what you want mate
The revised DV from VW is only about ÂŁ30 and has recently had good reviews.
Picked my 007p up for ÂŁ50 second hand and then bought a service kit from Forge to make sure its not leaking. Brand new they are just abit over ÂŁ100 i think.
Noise wise, combined with a standard airbox, there wasnt that much difference. It does make the turbo more audible, but not loud by any means. If you want loud, you need an open cone filter.
Forge ones are pretty bulletproof as they can be taken apart and regreased and resealed along with a new piston if you so wish. The new OEM ones should last a good while but may eventually need replacing again but for the price of them its not such a big deal.
Yes they are easy to fit, destroy the old VW clips holding the DV on, swap the DV, refit hoses and secure with new jubilee clips and voila.
