Denso Spark plug

I went with Denso's on my 1.8T because that is what I had on the shelf. but I have ran anything and everything in vehicles over the years, and found that there is not much different between the different types.

Pros: not much difference

Update: went Bosch for the plugs and ngk for the coils, the manufacturer plugs and coils were still in as if no one has touched them since the car was bought, I’m the third owner I believe. Each spark plug was toasted, easily double the recommended gap, and once I put the first two coils in (pulled code P0300, P0301,P0302) the problem entirely went away (coughing and sputtering exhaust, slow to accelerate, car shaking between 20-40 mph, rough starts) so I knew it was a go ahead for the rest of the coils. Feels like a whole new car all around, I can tell the engine is thanking me by what she’s putting out now ????

Pros: problem entirely went away
Cons: spark plug was toasted
Mileage: 179000 km

So new Bosch plugs and red-top coils seemed worth the $109. Old spark plugs were pretty crusty, which made me feel better about doing it.

Pros: worth the money
Cons: old plugs were crusty
Mileage: 42000 km
