Looking to get new plugs. Where do you guys buy them and what type should I get. They are for the Infiniti I35.

I am looking at the following:

Bosch IR Fusion, part number 4516
Bosch Platinum 4+, part number 4431
Denso Iridium IKH16

What are your recommendations?

 

I just bought some NGK Iridiums for the junker CL. I got them from sparkplugs.com dont remember exact model number, but it was something like ZFR6FIX

 

I'd put in whatever the factory did. They know the engine better than anyone esle.

 

I'll check them out.

 

i've always used Bosch platinum plus 4's, 4 prongs and they all arch.

 

That's what I had in my last 2 cars. I like them, and will probably end up getting those. I just wanted to see if there is much of an advantage with the Iridiums.

 

Check to see if there is any sort of specification for the motor. I know some cars (like my old Golf) would misfire and sputter on anything better than the cheapest copper plugs out there. I just put some NGK Irridums in my Taurus and so far so good.

 

Bosch plugs tend to be a crapshoot in Japanese cars. They work fine in some, horrible in others. Luckily they have a five year warranty.

 

in what gassers we have in the farm(4-wheelers,snowmobiles, smaller trucks,etc)
we run NGK.
if you're not hip on NGK i'd suggest Denso that's what Honda runs out of the factory.
