Yeti 1.2 (2015) CYVB

 

As is my ritual when I get a new (old) vehicle, I always change the plugs. 

 

I tend to always steer towards NGK plugs does anyone know if these are suitable? (one site will say suitable, another will say incompatible etc)

 

NGK 93231 / PZKER7B8EGS 

 

Also does anyone also know the torque settings for the coil packs and the plugs themselves. 

 

TIA

Nm setting

For future ref if anyone is looking for Nm settings

Ring TPS, they will give you a good price and also the part number. They might even process an account with you if you decide to buy from them.

I have always had good results from NGK plugs, but the market is awash with counterfeits so get them from a trusted supplier.

 

NGKs own partfinder shows the number you quote above.

 

Some makers produce both OEM and Aftermarket ranges, which may or may not have detail differences. This might account for alternative part numbers being quoted.

 

I changed the plugs on my 1.4 CAXA engine and found that getting the coil packs off was quite tricky - they are quite tight and the cables are short.  There are various plastic mouldings to hold things in place and these seem to want to fight back. I ended up making my own extraction tool to give an upwards pull.  Like all these jobs, it would be easier next time knowing what to expect.

I changed mine using one of these to remove the coil packs. This made it simple.

Be careful removing the 4 pin electrical connectors, holding the locking tab out with a little pick releases them easier than the side press tab.

You need a slimline socket to get down the cylinder head recess holes.

I smeared a little silicone grease on the coil pack base on refitting 

 

The NGKs worked a treat.

Coil packs were a bit more stubborn than on previous motors but managed to pop them out with a bit of brute strength.

Wish I'd seen this post before I did it, coil packs were way more stiff than previous cars I've had, bit like there's a vacuum in there.
