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[:-].

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]http://i101.photobucket.com/albums/m...7/S5000450.jpg [ul][*]Uncrew the two screws on each coilpack using a 5mm hex bit[/ul]Attachment 62041 [ul][*]Take a 5/8 deep socket and at least a 6" extension and remove each of the spark plugs[/ul]Attachment 62042 [ul][*]Apply a light coat of anti-seize to each spark plug and put them back in. Screw the coilpacks back on and attach the clips. [/ul]

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.

Whats better a hotter range or colder?

P.S Just to let everyone know I ordered the pulstar plugs for my 1.8T cost me over 100$ I will write a reveiw on them as soon as I get them in the mail and get them installed.

RE: Replacing Spark Plugs
 

I changed mine a few months back. Good thing to. My old ones were fried.

RE: Replacing Spark Plugs
 

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

I get 40K mi. from NGK PFR6Q platinum plugs.
They sell for $11 each@ rockauto.

RE: Replacing Spark Plugs
 

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

RE: Replacing Spark Plugs
 

Yeah. A cooler plug-BKR7E for 18+ psi. A hotter plug- BKR6E for stock or some chips that peak bellow 18psi.

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