    Rated 1 out of 5 by Nope Didnt feel anything, not recommending. Improved nothing. 04 May 2016
    Rated 5 out of 5 by Brilliant product This stuff is amazing! I used it in my mum's Peugeot 206 a few years ago which was starting to feel really sluggish and returning appalling fuel economy (260 miles per tank). I put some of this in, floored it for a few miles and it felt like a new car. Throttle response was much improved and was getting nearly 400 miles on a tank. Other places sell it cheaper but Halfords seems to be the only place in my town that sells it. Overall I'm very pleased. 15 December 2015
    Rated 5 out of 5 by Good product. Does what it says on the bottle. I'm normally skeptical about fuel additives but I thought I'd give this a try since it was on sale. Not going to lie, the results are spot on. I noticed that on my second drive, the engine seemed to run a lot smoother and the throttle seemed more responsive and eager that before. Not had chance to test out the MPG yet. I also noticed that the engine had a bit more 'pull' when going uphill when in a higher gear. 04 August 2015
    Rated 4 out of 5 by Good product My engine management light has stopped coming on since I used this. So all good in my view. 02 September 2014
    Rated 4 out of 5 by Good product despite being sceptical at first Ran the car on a dyno before adding the additive through a full tank as directed. Put the car back on the dyno a week/full tank later and had a 3 bhp increase. 30 March 2013

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
