On a Civic, the stock plugs are made by NGK and the performance is fine even for tuned applications. Unless you are doing serious modifications such as forced induction, etc.. there is not need to change the plugs to aftermarket ones. They may offer more spark, etc.. but it's unlikely that you will notice a difference.

Most forum members agree that the stock Champions are just as good under most conditions as considerably more expensive plugs, including Bosch Platinums. Some have said that the "performance gains" claimed by some are due only to the use of new plugs, rather than special new plugs. The best oil is synthetic - it provides more protection during cold starts, when most engine wear occurs, and is more durable than standard oils. See similar questions...

A Champion D-16 can be used in all British Seagulls. If you have the Mk 1 and Mk 2 ignitions, then you use a gap of .020". If you have the Mk3 Wipac ignition, then your gap must be no less than .035" You should always carry a spare plug as it is the easiest fix on a seagull. Note that the very early seagulls - the 102 styles specified a gap of .015 to .018". This was due to the fuel used at the time and now a gap of .020" is recommended. See similar questions...

NGK bkr7e's are a great choice and my recommended plug but you can also use Zex plugs or any plug that has a similar profile to the NGK's as well. See similar questions...

No, you can not use a copper wire, or solid core harness. You have to use a noise suppression (a.k.a. resistive) spark plug wire in order to prevent unwanted RF noise from damaging the controller. Electroair supplies the appropriate harness wire with attaching hardware to complete your installation. See similar questions...

Both the VE and VG use the NGK plug as a stock spark plug. The VE requires a platinum plug, which can run fairly expensive, at about $9/plug. I don't have the part numbers for this plug yet. The VG also uses an NGK plug, but they are non-platinum and cost just over $1/plug. Part numbers: Standard Type BKR6ES-11; Hot Type BKR5ES-11; Cold Type BKR7ES-11; Plug Gap 0.039 - 0.043 in (1.0 - 1.1 mm). Check your coolant level. this is a common problem. See similar questions...

A3. Stainless steel cannot transfer heat fast enough to allow the spark plug to properly cool. It is also very difficult to break off the installation tang during an in-frame repair. See similar questions...

The spark plug is what causes ignition. It takes a voltage surge from the coil through the distributor, and produces a high voltage spark that ignites the compressed/boosted air fuel mixture within each cylinder. If everything is working properly and your fuel curve is set appropriately, an even and safe burning of the compressed mixture will result. The piston is pushed down, the crankshaft turns, and the engine runs efficiently. See similar questions...

The thicker the wire, generally speaking the more conductivity you will get. But in mildly tuned applications, you will not likely notice a difference. More often than not, people change them more for looks. See similar questions...

A13. Most plugs are now preset at the factory and shouldn't need to be adjusted. Please refer to your owners handbook/manual for the correct gap setting. If you do not have the data available then we may be able to check it for you. See similar questions...

Moroso and Mr. Gasket make loom kits that route the wires across the top of the valve covers and then drop a pair of plug wires almost straight down between the header tubes. But they only work if you have 90 degree boots on straight plug heads (some angle plug heads have spark plug clearance problems). If you keep the slack in the plug wires to a minimum, the plug wires survive just fine. These kits are especially nice if you have A/C as they allow a fairly tight clearance to the head.

The size of the plug varies from unit to unit. We recommend checking with your Poulan or Poulan PRO servicing dealer for exact details. Follow the spark plug replacement procedures in the operator's manual if doing the work yourself. Back to Top >> See similar questions...

The fuel filter is located in the fuel tank.We recommend changing the fuel filter yearly. To remove the filter, drain your unit of fuel and remove the fuel cap/retainer assembly from the tank. Pull the filter from the tank and remove it from the end of the fule line. Install the new filter and reassemble. Back to Top >> The air filter on your unit should be checked and cleaned every 5 hours of use. See similar questions...

Spark plugs are typically available in different heat ranges. The plugs that we sell on the NEUSPEED website are suitable for stock engines and mildly modified engines. However, there are times when you might need plug that performs slightly different from our standard listing. Hot" and "Cold" refer to whether the plug is higher or lower on the heat range scale compared to the standard replacement plug recommended for your car. See similar questions...

If you have a 2000-2004 Isuzu, make sure you only use Denso K16PR-P11 spark plugs. Check the link below to buy them for 6.80/plug (note the dealer charges about 17/plug) If you have a 2000-2004 Isuzu, make sure you only use Denso K16PR-P11 spark plugs. The 2000-2004 engines have the GM/delphi "ion sensing" ignition system where the spark plugs are used as a sensor (when they are not firing) to measure the electrical resistance of the gasses in the combustion chamber.

Indmar has not tested and cannot approve the use of split fire spark plugs. Incorrect spark plugs can foul, cause radio frequency interference, cause the engine to run poorly, and may cause severe engine damage from detonation. Your warranty does not cover damage caused by the use of products not recommended by Indmar. The operator lists the recommended spark plug for your engine. See similar questions...

Despite ads by certain wire manufacturers claiming increased power from their wires, this is not a reality. Unless your present set of wires is old and damaged causing misfires, these magic wires are not going to increase power. For some excellent reading on ignition wires go to www.magnecor.com.

R = Resistor (Radio interference suppression, not vital(?)) 7 = Heat Range (lower numbers = colder plugs) D = Length (?) See similar questions...

Many of the performance shops recommend you change them every 30-50k miles. I am not convinced whether this is really needed. The general rule of thumb is that the wire's resistance should be around 12kOhms per foot, and not more than 50kOhms/foot. Check also for the specific values in the car's manual.
