could anybody tell me the gap size i should run with these plugs? dont they come .40? thanks in advance
one more? when doing wires someone told me there is a hole in the block, and that would make it easier to route my wires! does anyone know what im talkin about?

 

They should come gapped at .50 which is what you want. Check with a feeler gauge just in case they got banged around. And there is no hole in the block to route wires, use stock looms.

 

Also, in case you forget again, it says what the gap should be when you open up your hood, look at the radiator shroud.

There's no hole in the block to route wires. What they probably meant was on the passanger side, you can route the wires behind the accessory bracket, as there is a space or "hole" between the block and the accessory bracket. This is handy if you run aftermarket wires that are thicker than the stock 7.5mm wires as the thicker wires are tough to properly capture in the stock holders.
