It fit easily seems to not be leaking air very happy the car has more torque now and feels so much quicker.

Absolute rubbish. Wasn’t holding when we bought it and even after installing it despite this, failed less than 200 miles later causing a vacuum leak. You’re better off paying extra for a used genuine part or a new OEM spec one to save the extra hassle and money this part will cause you.

Works no fault codes

Bought this as my car was showing p0171 and p0174 codes. I could hear the old one rattle a tiny bit so reckoned it was this. When it arrived I noticed the o ring seal on the new unit looked really bad, but I thought I'd try it anyway. Fitted it to the car and the same codes where showing, even tho the new disa worked fine and I had a noticeable increase in torque. So I stripped the entire intake system down thinking I must have another leak, with no leaks showing. I then went back to the new disa valve and noticed it wasnt sitting flush to the manifold as the old one was. The o ring on the new unit wasnt doing its job and was still leaking, I've had to order a disa o ring from another supplier to replace the seal that has arrived to me faulty. The product does the job, but poor quality means it's not worth the hassle

Arrived next day and was a very good price. Was back on the road without the Red Arrows style plumes of smoke within 24 hours!

Got vacuum leak

Did not fit snug so had air leaks still
