Had my 2017 Ignis for a couple of years but only found this great site a couple of weeks ago. Car needs servicing this month and I had the shock of my life because the dealer charges £130 for 4 spark plugs. The Suzuki handbook sais NGK ILZKR6F11 but nobody seems to have these. Any help welcomed.

Welcome to this forum. I'm guessing your Ignis has covered fair mileage since plugs only need changing every 63000miles / 84 months. Iridium plugs of the correct part number are pre-gapped and can simply be fitted.

  • Remove and install plugs with the engine cold.
  • Before removing anything, in order to prevent muck falling into a cylinder, clean the recessed area around the plug tubes. Blow the area clear or use a vacuum cleaner.
  • You can either disconnect the electrical connector at each ht coil or leave connected and just unclip the connecting leads.
  • Remove the bolt from each ht coil and pull out each coil complete with the ht connector tube
  • To remove the plugs use a 16mm plug socket with a long extension - the plugs are deeply recessed.
  • Use the plug spanner to grip the plug and lower into the plug recess. Plug gaps are pre-set. You can lightly oil the plug threads but don’t use anti seize compounds like Copaslip.
  • Screw plugs initially by hand only, then tighten until the plug seat contacts the cylinder head. Use a torque wrench to tighten to 23Nm or tighten by 90 degrees - a quarter turn of the wrench.
  • Thoroughly clean each coil assembly with a cloth moistened with WD40 or similar. Ensure the rubber seal is in place and fit the coil assemblies so that they clip to the plug.
  • Refit the securing bolt to each coil. These thin bolts are fragile and just need to be nipped up - don’t over-tighten.
  • Refit the lt connectors / refit the lt cables into the securing clips. The length of the lt leads is such that it would be difficult to make a wrong connection.

Spot on ***. Bought a 16mm plug socket for £4.80. Changed the plugs in half a hour even though I was taking my time to do everything properly without rushing. Might just be me but looks that the car is running smoother with more zip. Thank you.
