Guy's - This may sound really stupid but here goes!

Just got my first Scoob, a 94 STi, and set about the task of doing a little service (Oil, Oil filter, fitting an induction kit) but for the life of me can't find were the spark plugs go??

Am I being hopelessly stupid or did Subaru design this excellent piece of engineering in such away that looking for the spark plugs is so frustrating it makes you wanna scream!

All advice WILL be apprecieted thanks.

 

your plugs are down the side of each wing so to speak on the ends of the engine, if u look down u should see ur ht leads.mark

 

Sorry to sound stupid - upid again, but are they easy enough to change? Or will it bring me to tears of frustration and cut knuckles trying!

 

If your going to fit an induction kit, the plugs will be easy to get at when you remove the old air filter box. L/H side.If you remove the washer bottle R/H side, you can get to the plugs.

Not easy,easy. You'll need to remove the battery, water bottle and some of the intake piping to gain access and the the 4 ht coils sitting on top of each spark plug. You then need a socket, a deep 16mm with extention bar.

you wont need to remove the battery, although they are level with the inner wing

Drivers side

1. remove air box complete
2. carefully remove HT lead using grippers on lead
3. use a 16 mm deep socket or a spark plug socket and a suitable combination of extensions (you'll see why) and remove plugs, best to do one at a time. the rear ones are a **** to get at.
4. replace plug, care not to cross thread and repeat removal in reverse.

Passenger side

1. remove washer bottle, or move it so you can get access.
2. same as above but a front one is a bit cheekier to get at.

its all down to your tools TBH.
