    Rated 5 out of 5 by from Things are not as they seem.........But all ended well..:-) So ordered new Spark Plugs as they were not in stock to pick up off the shelf and they arrived as promised.....I opened the box and too my horror they looked different from the ones I removed......To say I was annyed was an under statement...Such an easy job as ordering the recomended plugs created a huge explosion in my head.....I needed the Plugs NOW......The problem was the bit that plugs into the HT Leads were bigger than the ones I had removed...I was getting prepared to take them back to Halfords with a stomp of my feet then I thought I would ask the world famous Google..And hey prestow the issue was resolved..You had to take the larger cap off..As they need a set of plyers to remove the caps this was not obvious on first look..No instructions on the box so a muppet like me had no clue that they were the right ones afterall...Maybe a note on the description would have helped.. Suffering with Combat PTSD and Anger issues assosiated with PTSD is not a good mix when you think everything is going wrong...Rambled on a bit but hopefully this will help prevent soeone elses meltdown...

    Rated 5 out of 5 by from Power to the plug The bike was misfiring on the original NGK twin head plugs. Stuck these iridiums in and issues resolved. Time will tell whether they are worth the extra money for longevity but I am well pleased so far

    Rated 3 out of 5 by from Iridium Plugs These replaced the OEM plugs in a 2000 reg Kawasaki ZX-12R. Stops all of the misfiring and poor throttle response. Expensive from Halfords but they did have them in stock where others never,

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.
