Review
Tried this awhile back, quite an awsome product. After the treatment from this product my engine is pretty much quiet and smooth. Sceptical with the product at first as I couldn't find any much information from Mr Google. The workshop guy ensure me will not be a problem as they are award the TUV mark to prove prove their quality so decided to try. Currently for fuel consumption wise also alot better than last time. I can see alot of similar products out there in the market so will probably keep my options open for others but can't deny this works.

What I like
Engine makes lesser noise and a lot more smooth

What I do not like
Not much reviews out there

I installed this on
Nissan Sylphy

Review
Known this product through a recommendation from a friend. I would say not too bad as I do not really find much reviews around. It reduces the noise coming from my engine and feel more power compare before the treatment. Works well and might stay on to this in the future. Yet to really check on the fuel consumption part as didn't really have time to keep track but seem to last longer now. Maybe will check the receipts to see the difference when i am free. Other than that, i am pretty much happy.

What I like
Reduced noise and better power

What I do not like
nothing for now
