A high quality product that far exceeded my expectations. Fairly simple to fit with the helpful tip of cutting down the longer leg on an allen key, however I also found tapping a piece of allen key into a spanner was a good option. Retains the stock recirc sound, yet holds boost for a much harder pull. I would highly recommend this!
Great fast delivery. Haven't fitted item yet but looks amazing quality, would highly recommend!
Quality product sounds almost the same as standard recirc however allows turbo to spool up better,built to last due to no diaphragms internally... id advise to remove the whole air intake to allow better access to recirc on corsa d vxr.
Thank you for the review, we are glad you are happy with the product.
Great product and very fast delivery. Absolute pig to fit thanks to vauxhall but a little adaption of Allan key and perciferene it's on ha
Brilliant item, abit of a pain to fit due to vauxhall but we'll worth buying A*
