I have a 2003 4.7 Durango with CA emissions. I had changed one a few years ago with a cheap brand from RockAuto.com, now I have another one out. I planned to go to the dealer and get all new ones. I was reading some threads on here first. I read that NTK is what they have at the dealer and read in a different thread that these NTK shouldn't be used just get them from the dealer. lol. So my question is, is this the brand that the dealer carries NTK because these are also available at Rockauto.com part # 23527 & 23556 (please correct me if the part # are not right).

 

Well...I'm thinking I'll go with the NTKs over the Densos unless I hear otherwise.

 

I've always stuck with the Denso's on the D... never had issues.

 

Have you had to change any twice yet?

 

On the D... no.. I changed them when i bought it almost 3 years ago... no issues yet but its only been 3 years...

Now on my old Chevy yes but, i owned that almost 15 years...
