It depends how good it its condition, although I changed a new set of wires because the engine oil seal was leaking causing enlarged rubber header.

You are supposed to, but it doesn't mean you should I changed mine at 100,000 I would say skip them for now and next time you change your plugs change your wires

No, you don't need (not required/necessary) to buy a new set of spark wires unless you have money to waste or are bored. You can measure resistance of each plug and determine the health of the wires. Look for cracked insulation, heat spots or fitment, but if your car runs fine, (doesn't misfire, stumble), keep the wires.

I found another plug at Walmart(automotive/ lighting/wiring)& took what parts i needed that one to make the original work. If your not comfortable swapping parts,you can splice the wires to the new connector or hard wire it to a fused switch.

Hi, Yea this set I bought had 12 spark plug wires in the box. I bought it for a M112 6-cylinder engine Mercedes so it was the right one. Hope this answers your question.

Spark plugs are appproximately gapped from the plug manufacturer. You should consult the user manual from the ENGINE MANUFACTURER for the correct gap.

You should use the spark plugs that are specified for your vehicle. The correct spark plug can be found in your owners manual.

Easy if you are replacing the old ones, 2 wires and a ground wire. If this is a new install, as opposed to a replacement, you will probably need the services of an electrician. We love ours.

You don't have to but it would be a good idea to do the coil plug wires and plugs which would be a complete ignition system tune up. All Speed Customs

You need a code reader or you can buy a new coil and keep swapping cylinders till you find it. It could be the spark plugs too

When you are sure of the spark plug you need, then order it from Amazon. They are the best for price and delivery service. RP

Check to see if there is a spark between the spark plug and the wire if there is this is not the problem. I have no idea if this will fit your model.

My first guess would be to ensure there is no oil or coolant around the spark plugs, boots and wires. Verify he did not cross some of the spark plug wires. Spark plug coils could be failing.

Not sure how long the wires are, but, I have them on older restored motorcycles and had plenty of wire with the tach mounted on the handlebars. If the long black wire is too long coil it up and tie off. Do not try to cut and splice! You can cut extra red wire that wraps around spark plug wire as it will be too long. Hope this helps.

My best answer to You is to go to Checker O'reilly or Autozone and ask them the number for the sparkplugs for your vehicle and ask for platinum plugs to start with. They'll look it up..

No, it looks like you need 09850 see here: http://www.ebay.com/itm/Bosch-09850-Spark-Plug-Wire-Set-/281087874091?pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A1999%7CMake%3AMercedes-Benz%7CModel%3ACL500%7CSubmodel%3ABase&hash=item417224942b&vxp=mtr

I don't see why not. Comes with different thread sizes for spark plug holes. Should work fine.

I have always just too plug wire loose and stuck a screw driver in the plug wire hold it close to the plug and pull starter rope to see if I had spark. If not starting I would suggest just replacing spark plug and make sure has fresh gas with correct oil mixture.

Its been several months since I changed my plugs and wires. You need to list your vehicle on the Amazon site for Automotive and it will tell you whether these wires are correct for your '04 vehicle. My Suburban is an '01 and there are subtle differences that are introduced with newer models. The old wires will be difficult to take off at the plugs which means you should have replacements before you start due to the possibility of damaging the old wires. New plugs are set at .045 gap which is correct versus the .060 previously required at least for my vehicle. You need some antiseize for the new plugs and silicon spray for the boots of the new plug wires. Its been several months since I changed my plugs and wires.
