Ok so im looking to replace the sparkplugs with either Bosch +4 or NGK iridium ix ! and wheres the cheapest i can find them for and wires ????

 

I got my Bosch from AutoBarn via Amazon, which was the cheapest way I found.

Check your engine, what wires, these things don't have traditional sparkplug wires

There's coil packs that sit on top of the valve cover above the spark plug holes 4 on each side of the engine. Unplug the wire connector on the coil packs then take the two bolts off (10mm) and twist a little clock/counter clockwise and pull it straight up. There are two rubber booties attached to the coil pack that travel down the sparkplug holes that carry the current the spark plug.

<edit> Here's a pic.

<edit #2> When putting new plugs in be sure to use antiseize lube on sparkplug threads.

Ya thats what i ment lol

 

whats the part number of the Bosch +4 for the 5.7 and where do you see the part number on amazon ?(great find by the way real cheap i wounder if they sell mobile 1)

 

06Hemiazy,

Put the new plugs in (at great expense) and run it at the track and let us know. Also, see if your MPG actually goes up (take a trip now and the same trip after the new plugs are in). For the absolutely miniscule difference you'll get, at the cost difference, I'd be shocked if anything changes.

The new technology with the stock plugs and coil packs have narrowed the gap (sorry) of the aftermarket vs stock plugs difference.

Save your money .
