Seems a very good price for what they claim to do.

Looks interesting but sounds too good to be true at those prices.
Mine were £10 each to test and the bad one £100 to refurbish.

They don't give a price for diesel injectors though.

Their YouTube video is interesting. My C5 has done over 130K miles and so I wonder what state my injectors are in.

The info suggests that you could have lost power and efficiency in as much as 50 to 60k miles.

It would be interesting to know how this cleaning compares to say using REDEX or Millers injector cleaning additive.

Redex (ive found) is a waste of time, i did have my petrol injectors sonic cleaned at Lucas when they were still about and it smoothed idle out nicely, about the same price too, once they have the machines to do it the actual cost of cleaning a set of injectors is almost nothing so i would think they are ok, i will send the turbo injectors off when i get to that stage, derv injectors on the other hand will be much more expensive to sort out.

Looks ok to me.

Any V6 owners should take a punt at the set of injectors they have as well, though they are down as only for an XM im sure they would fit pugs and th xantias

Think i may get the ICV and injectors off a scrapped TCT and send them off there, better to have a spare set as well me thinks...

How easy to take injectors out?

Had my injectors out recently, got new o rings and caps from Mr Injector, soaked the injectors in Xylene which got all the crap off, refitted and the engine is without doubt smoother and quieter.
