Hi,

I just bought an 05 Dakota V8 Magnum Quad Cab and the spark plugs need to be replaced. I read the posts about Iridium spark plugs which gives them a good review and thus I am looking to buy a set. What I would like to know is which brand does each member here recommend as the best factoring in price?

Thanks,

 

Went to the Densco site, them little puppies are spensive....

 

Last week I replaced my Autolite 3923's with NGK Iridium XI. I have been very happy with these plugs. Work much better in the HO.

 

Thanks guys. I have found Denso Spark plugs on a few Canadian websites for about the same price as NGKs. I will let you know how the Densos are when I get them.

Are the NGK Iridiums you guys are talking about part # ZFR6FIX-11 for the 4.7? Also what gap?

 

Check out sparkplugs.com It gives the numbers of plug and gap for the HO and non HO engines. Check the vin # on truck I think 7th or 8th # to get the N or J code of engine.

 

The one I used was stock 6441, part zfr6fix-11 gapped at .044. Mine is an HO.

 

N or J specifies whether it is the HO model or not, I just can't remember which is which...

 

N is the non HO model and J is the HO model...
