Hi Guys

I have currently been on an investigation trail on why my 1.8Turbo seems a little weak.

Done the usual test by unplugging the MAF, the car runs the same so I have been instructed to replace my N75 valve.
Doing my interweb searches I see there are several different variants of this valve, the most potent one being the “J” valve. Seen here:

I would happily purchase this one but some users say they have had problems with it.

If anyone has had with experience with these different N75 could you please advise me on what one to go for?
