Undo the retaining clip and remove the rubber airbox to throttle body pipe...



Remove the air intake pipe, this is just a push fit...



Undo and remove the two 10mm headed bolts (circled in red) and pull the complete airbox upwards near the green circles to remove the push fit retaining pegs...



With the airbox removed you can see the 4 coil packs and the 4 10mm headed bolts that have to be removed...



The first three coil packs can be removed with the wiring connected, place these gently on the front slam panel...



Disconnect the wiring from number 4 and remove the final coil pack...



Using a 16mm Spark Plug socket remove the spark plugs...



Here you can see the new Denso Iridium Tough Spark Plug next to the original NGK...



Replace all 4 spark plugs and torque to 25Nm (18.4lb-ft)...



Replace the coil packs and tighten the 10mm headed bolts...



Airbox replacement is a reversal of the removal, pushing the two retaining pegs (1) into the rubber grommet, 2 x 10mm headed airbox bolts (2) , tightening the Airbox hose clip (3) and re-fitting the air inlet hose (4)...

Nice one Karl.

Nice easy guide, thanks for that.

Can someone confirm the plugs on a 1.6 petrol MA16 engine please ? So many variants, thought Denso VKH20 but they do a VKH20Y and same plugs vary from £4.99 to £16.99 a plug or am I better sticking to NGK is that the ILZKR7D8 ? I know there are rip off copies out there so anyone recommend a supplier ?

Denso UK specify DENSO part number: SK20HR11 or DENSO part number: IKH20TT for the Vitara M16A

They also have a "where to buy" page to ensure genuine bit in general I have yet to receive any fake Denso plugs
