The estimate from the dealer was $3400 - yikes. Their labor was only about $600 and the coils were $216/ea, wires $56/ea (need 16), plugs $15/ea (need 16). After pricing out the off-brand parts online I can save about $1629 on parts alone...

After dwelling on it for the night I decided to grind the dealer a little bit (ended up getting 20% off with competing dealer coupon) and just let them do it. Don't get me wrong because this actually would be a fun thing to do compared to my day to day work life but not sure if it makes sense at the end of the day. I would rather have the dealer do it because in the mean time they look at those cars everyday and may notice something else wrong that I would miss, not to mention you can't complain when they give you a 08 loaner for free (I dont have a 2nd car). Also the work is fully guaranteed and it looks better at the end of the day to have the paper trail when/if I sell.

Overall this car has been amazing to own and extremely trouble free so i am happy

Thanks again guys!
