Shop O'Reilly Auto Parts for the best spark plugs, spark plug wires, coil boots, and other spark plug and ignition system parts for a complete tune-up or repair. If you're unsure of what spark plugs your car needs, check out our helpful articles on how to choose the right spark plugs, how to set spark plug gap, and much more. Replacing spark plugs is part of a regular tune-up, so if your spark plugs need to be replaced, you should also consider replacing the spark plug wires or coil boots to restore optimal performance. Signs of a bad spark plug include misfiring if your vehicle has difficulty starting, a rough or loud idle, reduced fuel economy, trouble starting your car or accelerating, an illuminated Check Engine light, and more. This damage can affect your vehicle's ability to ignite the fuel mixture and prevent you from starting your vehicle or running the engine. A non-working spark plug can also be caused by a failing ignition coil, spark plug wire or boot, or a damaged connection from constant heat and long-term use. Spark plugs may also be fouled by overly-rich fuel mixtures or oil contamination, which can cause engine misfires and allow the spark plug to only operate intermittently. Additionally, pre-combustion can cause the spark plug electrodes to fail prematurely. If the spark plug electrode wears down too far, the gap may become too wide for electricity to arc, resulting in a weak spark or a complete lack of spark, and an engine that will not start. Although they're designed for lasting performance - around 80 to 100 thousand miles - spark plugs wear out over time as the electrode material degrades. Without healthy spark plugs, your car will not start or move or may experience a loss in performance or efficiency. The spark plugs on your car consist of a center electrode that receives power, and a ground electrode that completes the circuit to arc, making a spark. Perhaps it caught measeles whilst on its trip.Spark plugs receive power from the distributor and/or ignition coil(s) that they use to create the spark needed for combustion, and are crucial to starting and your vehicle's engine. I'll report back on the pump, which is clean and has lots of little red paint blotches dotted about it. I'll also go to try and find the NGK plugs and see if they do any better. Incidentally, I've used Joe's excellent linkage tour to check that and it's spot on. I certainly don't have the expertise to be able to say 'what utter madness' to the gentlemen who did it, much as in my head when I heard what he'd done I was screaming something altogether more colourful. Not much I think I can do about it other than hook it up and see how it runs. The chap who did drill said holes is a semi-retired older Dutch gentlemen who, apparently, seriously knows his pumps and even bought some of the Bosch factory testing eqpt when they were getting shot of the old way of doing things 'way back when.'Īnyway, I now have a pump with more holes in it that before it went to get a service, although they're on the inside. I would not drill any holes in my pump either, but this is after the fact. Question: assuming a hotter plug will help, what then is the best NGK plug that people feel I should opt for? (Once and for all!!!) Can't wait to see how it runs and will refit ASP). (My FI pump has been away for a re-do and has now come back with an apparently scary approach to stop the oil building up inside it - something about drilling 2 holes inside to allow the oil to return. I have a newish set of BP5ES plugs at home that I've cleaned up, but they end up black as pitch each time I get the car to run. I have managed to find but 4 of the things in 3 months of looking. (Can't find the decarbonising stuff anywhere that people talk about).įrom what I read I understand that I should put in hotter plugs to help things along. It also has poor compression but then, it hasn't been driven much and is probably caked up. The cross references are for general reference only, please check for correct specifications and measurements for your application. My engine is no spring chicken (it's actually a 2.3l mercedes engine, but you know what I mean). There are 178 replacement spark plugs for Bosch WR7DC+. From what I've read, particulary by Dan and Joe, the cars run rich as they grow older. I have a car that, when it runs, runs rich. ( of 2)Ī little advice from the experienced would be helpful. This table shows the most common Bosch/NGK equivalents.
