FR78NX Bosch Super 4 Spark Plug x4 is rated out of 5 by 5.Rated 2 out of 5 by Gazjones1962 from Not worth the money Needed new plugs for my Toyota Avensis so decide to try these. Put them in with great anticipation and was instantly disappointed. The starting and performance want not as good as the NGK's I had taken out even though they had done 25k miles. Thought the ECU might need to recalibrate so left them in for a month. No difference so replaced them with NGK and what an improvement. Wish I hadn't fallen for all the sales hype and wasted the money.Date published: 2017-05-13Rated 5 out of 5 by Cain26 from 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.Date published: 2014-12-04Rated 4 out of 5 by Daykes89 from 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 10,000milesDate published: 2013-03-15Rated 5 out of 5 by MajorOverhaul from 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.Date published: 2012-07-01Rated 1 out of 5 by hobby544 from wrong item unfortunately, this product did not fit my nissan almera tino, had to return product and obtain correct spark plug, this was most annoying as i hade to make two journeys, 30 mile round tripDate published: 2011-10-08
