Default Replacing Spark Plugs

Tools Required [ul][*]Socket Wrench[*]5mm Hex Bit[*]5/8 Deep Socket[*]6" extension (or larger)[/ul]
Recommended Plugs [ul][*]Bosch F6DTC[*]NGK BKR7E[*]NGK BKR6E[*]Bosch F5DPOR (expensive)[/ul]NGK BKR6E will be good for stock cars, go with BKR7E for chipped cars. My personal favorite are Bosch F6DTC, never had a problem with them and they dont need gapping. Last far longer than the BKR6E's too. I've been wanting to try the F5DPOR side fire ones, which also dont need gapping, but they are $16 a pop[:-].

Heat Range Comparison


For gapping, you want to be between .28 and .35. Stock cars should run towards the higher end, while tuned cars should run towards the lower end. Both .28 and .30 are popular for chipped guys.

And you should be changing BKR6E or 7E every other oil change (10k) and the F6DTC and F5DPOR will last 25k+ but i always change them by 25k at the latest.


Directions [ul][*]Remove the engine cover if you still have it on for some reason[/ul] [ul][*]Lift the metal clip on the coilpacks and pull the plugs out[/ul] [ul][*]Uncrew the two screws on each coilpack using a 5mm hex bit[/ul]Name:  S5000449.jpg

Changing spark plugs does not create power but it does free up lost power. I gained 2 psi back by changing plugs and the car seems to run stronger

Nice result from the plugs - always good to relocate missing power

also add the fact that 2.8 guys don't need a 5mm hex bit. but instead a screw driver to remove the coolant reservoir and a 10mm socket to move the MAF.

stock cars run a hotter plug, while tuned cars run a colder plug

Don't you mean to switch that around? The 7 for the chipped and 6 for stock?

Thanks for the walk-through. Is a shot of WD-40 OK to use for the anti-seizing compound?
