Good options, good value for money
Good product, a solution to save money rather than replacing the part ! Have done this about a week ago let’s see how long it lasts !

Works as preventative not if your CAT is stuffed
Would've been great if this stuff worked for me but my Catalytic convertor must be shot.They may have been a slight improvement but the engine & stability control lights are back on and it runs rough at times and struggles up hills, poor performance when pulling away. I suspect this would be a good idea to use every 3-6 Months as a preventative in keeping the CAT in good health as long as the CAT is in good health to start with.

Brilliant.
Use it as instructed on the Company official website. Works perfect, you will need to erase computer errors, eventually. Engine work smooth.

Surprised how good value
Great value for money 😀 transformed performance on a 2003 petrol and brought emissions to pass level. Spray as a mist into air body whilst engine is set to 3000 revs the revs will purge and judder after take for a spirited run 😉
