I have a 2003 Maxima with 180k. Code 0300 multiple misfires and no power…. I’m looking to replace all 6 coils, spark plugs , valve covers and oil change. Where can I get the best coils from? I don’t want the cheap Amazon or eBay parts at all. Only want quality parts

 

Hitachi

I have had great luck with RockAuto.

After a lot of research these are the injectors we went with (Hitachi):

These are the coils we went with (Hitachi):

These are the plugs we went with (ngk):

We also purchased these coil boots:

Darned if I remember if we actually used the boots or if the Hitachi coils came with boots so we didn't need the extra ones. I think we did not use the boots though.

 

I was surprised the fastest delivery of coil packs for my Accord was through Summit.

 

hitachi coils (all coils ive ever bought for any vehicle) come with boots

 

How many times can this question asked? I think this subject should’ve been searched first! The result will be the person purchasing AutoZone Duracrap, or cheap Amazon Crap…. Even though 10,000 ppl gave you the proper insight with a combined 100 yrs + Maxima experience….

 

Best name brand coils are made from HITACHI. AVAILABLE from carparts.com. Get irridium plugs. I got my valve cavers from import direct, comes with PCV valve. Make sure you replace manifold gasket before re installing Bank 1 manifold . Sure you're aware manifold needs to be removed to get to Bank 1 coils and plugs. Good Luck.
