    Rated 5 out of 5 by top quality spark plugs. engine starts up a little better. Peace of mine knowing my Peugeot has the recommended plugs in it and it now starts up a little smoother. Nice to know i have top quality plugs. 04 December 2014
    Rated 4 out of 5 by Fitted to 1.6 16v TU5FU engine (Petrol) Very good indeed has improved lower end pickup & fuel consumption. I now get around 46mpg! Before fitting these I was getting around 42mpg. However, they do seem to lose their 'spark' (wear out quicker). I replace mine every 10,000miles 15 March 2013
    Rated 5 out of 5 by Amazing change... Stuck a set of these in TU5JP4-engined Citroen to replace the original NGKs two years ago. They make a huge difference. With the NGKs the engine was rough and gutless under 3000rpm. With these is burbles along quiet happily at low RPM. Only problem is I'm having trouble getting another set, tried local Halfords twice and they were out of stock. 01 July 2012
