My feels like it’s running brand new with 100k plus miles ????
Some weekend progress after work, got the plugs changed out and fresh air filters are in.
I bought six OEM spark plugs at the Toyota dealership parts counter and it was $12!
ive been using the RS7 spark plugs(Gapped properly) and swap every 10k miles, but nowadays I do not run very hard, just cruise and occasional hard accelerations. Paired with APR coil packs, havent had any issues.
OEM Toyota plugs will probably last forever but it depends if your gas mileage is like 5 to 10 miles less that's the only way I would change the back plugs.
Spark plugs 100k miles - $25
120k miles on my 2015 a3 with a stage 1 tune. I did timing belt, tensioner, and water pump around 100k miles. Costed me like $1k. Also did spark plugs and a new battery, which was another $600.
Last thing on my agenda is the spark plugs. Got it with 131K and I’m pretty sure the previous owner literally sold it to avoid doing them. I know I should have done them yesterday, but god it looks like a bitch, even with Car Care Nut’s guide. I’m planning on doing the job with the new plenum gaskets, and ignition coils while I’m back there.
I do need to change the spark plugs. I haven't done that in 10+ years and 100,000+ miles. It just started misfiring slightly I believe (haven't checked the code yet), but it runs and drives well still.
I was given an "offer" to have my spark plugs changed for $368!
