Spark Plugs - What not to buy & do?
 
Hi Guys!
I got WJ 2003 Laredo with 4L i6. Seems like I need to change spark plugs.
Could you tell me which ones I should use and not use.
Where can I buy spark plugs on web?

Thanks a lot!

Just go to Advanced Auto Parts and buy some. Just buy the recommended ones. Don't buy the most expensive ones because you can cause damage internally in your engine. It actually matters.

i will say the bosch arent that great. I have the 4.7 and i had the bosch supers wich are coper cores. and they made idle jumpy and they made me have a hesitation when giving gas. i also tried the bosch platniums. i think there junk too. I bought some champions and wow the diffrence smooth as can be and runs great. just a thought, i didnt know the bosch where that bad until i got the jeep and started messing with plugs. stick with OEM if you can i beleave thats the champions...

If it ain't too late go NGK for the 4.0L i6 and never look back!

I'd say either NGK or Champion, both worked great in the 97 ZJ and the 99 XJ that I had ( both were 4.0L I6 ).

Too large?

Any specific model to go for? there are plenty of those and I got confused.

Use the appropriate v-power which you can find using the product selector on the ngk website - http://www.ngksparkplugs.com/part_fi...uv/default.asp

NGK doesn't sell directly, you'll need to buy them from one of their dealers. Pretty standard practice in the auto industry.
