If your car's spark plugs need to be replaced, you can do it yourself if you're comfortable working with tools. You'll need to refer to your car's owner's manual to find out what type of spark plugs to buy and how to replace them. It's a relatively simple job, but if you're unsure, you can always take your car to a mechanic.

Spark plugs are a vital part of a car’s engine, and they can last a long time if they are well-maintained. It is not uncommon for spark plugs to last 100,000 miles, and some can last even longer.

Permatex 22058 Dielectric Tune-Up Grease, 3 oz. Tube Review:


This product will shield the terminal end of your spark plug from water and other debris when used properly. In order to avoid getting the terminal end of the plug, which is deep inside the boot, the substance should only be put around the insulator area of the plug. An electrical insulator, or dielectric, works to prevent rather than promote an electrical connection. Grease is used to prevent water and other substances from creeping up toward the terminal end. I lubricate the plug's insulator, hand-tighten the plug into the head, and then repeat. Press the boot onto the plug after tightening with a tool to your desired torque (or just past snug). In order to stop debris from moving up the plug and eventually fouling the terminal end, the grease should create a barrier surrounding the plug insulator.



Permatex 81150 Dielectric Tune-Up Grease, 0.33 oz. Tube Review:


The exact application of the Dielectric greasy has not been agreed upon by the entire world. Some people use it for practically everything, but others support the claim that "it doesn't conduct electricity." Of course, it doesn't conduct electricity; instead, it merely aids in preventing corrosion caused by water, humidity, salt, and grime on the components. Where to employ it, though, is still up for debate. On the internet, I have observed users employing it practically everywhere.They demonstrate tests where it can be seen that if the link is carrying a significant amount of energy, it only requires a very little amount of conductivity, which is nearly nothing.I'm still unsure as to whether I should attach everything to my dirt bike and simply make sure that it is safe, or if I will only make things worse. I suppose I'll try a few first, and if nothing horrible occurs, I'll just keep going. :)Although not many people may benefit from them, I am sharing what I have learned.BTW, the tube is larger than I anticipated, which is great:)UPDATE: I've tried every connection I can think of on my Yamaha TW200, and so far I haven't run into any issues. All other things have been operating perfectly for months; the only thing I haven't tried yet is fuse. :)



Champion RC12YC Spark Plug, Pack of 1 Review:


Although this plug is typical for many tiny engines, be SURE to use the right one for your specific engine. In terms as reviewing a spark plug, I'm not sure what else can be said—it sparks when prompted. It came without damage. Having been a gearhead for many years, I advise sticking with name brand plugs. There are some incredibly strange plugs available, but they typically offer little advantages in tiny engines. This is also true for many cars, however outcomes with larger engines might vary greatly. Keep it simple; many engines come with the Champion 12YC plug out of the box, or at least mine did. This plug has been around for ages.



NGK (7131) BPR6ES SOLID Standard Spark Plug, Pack of 1 Review:


This spark plug is compatible with the Honda engine in my Sears Craftsman lawn mower. Thus, I start the mowing season each year with one of these brand-new spark plugs, a fresh blade, new oil, and a clean filter. Together, everything only costs around $20, and for that cheap sum, you get a mower that will endure for at least ten years.Although it still has a few excellent years left, this will probably be my final gas-powered mower. I'll probably purchase an HD battery-powered electric Ego mower after this one is gone. I'm done with spark plugs (and I can dump the ear plugs too).



NGK 7090 BKR5EGP G-Power Spark Plug, Pack of 4 Review:


NGK has always performed incredibly well for me. I have used everything they have to offer, even their iridium plugs. They all function well; in fact, their most common plug is suitable for everyday driving and routine oil changes. I've taken out regular NGKs from ancient cars and scraped off fouling deposits to reveal a gap that is still working and has little corrosion. These deposits simply seem to burn off more easily on platinum. (Just a hypothesis)I've always preferred plain platinum spark plugs. These are exactly what we need. I think it's better to get more affordable, reliable plugs and change them more frequently than to pay more money for pricey, "higher mileage" plugs and leave them in for longer. In this manner, I have brand-new plugs that ignite properly for a full burn. I am never comfortable leaving devices like iridium plugs on for the latter third of their "life." I always believe they begin to perform below expectations, and changing them earlier would be a waste of money.Spark plug replacement is also not difficult.



6 PCSNEW -- DENSO #4503 PLATINUM T T Spark Plugs -- PK16TT Review:


These work perfectly with my 2007 RAM 1500 V6 3.7L engine.One thing to keep in mind is that every spark plug was precisely pregapped at 0.035. According to the decal on my engine's compartment, my engine needs a 0.040-inch gap (which is odd because online RAM says it should be 0.044). Even though they will likely expand slightly, 0.035 is probably good to insert, I gapped them to the required size from my engine compartment (perhaps I was a little overly cautious). Make sure to check the gaps and make the necessary adjustments for your engine compartment. I haven't encountered any problems with these plugs yet, and they appear to be high-quality.



NGK 2667 BKR7EIX Iridium IX Spark Plug, Pack of 4 Review:


If you own an MKV VW GTI 2.0t, Amazon's "Garage" function will incorrectly state that "This product does not fit your vehicle." In actuality, it does fit. These precise plugs are available from numerous online VW tuning shops for usage in Audi A3, VW GTI, Jetta GLI, etc. So you're all set.These were put in, and the car now runs more smoothly. Strong pull across the whole RPM spectrum. On the stock BOSCH plugs, I had 59k miles. The factory plugs were beyond their prime and cause misfires when subjected to vigorous acceleration. My issues were resolved and the car now runs like new after I replaced them with these NGK BKR7EIX.The installation of the 2.0 t motor is straightforward, and you can get decent instructions and pictures online by searching Google. It was my own doing. Plugs are gapped correctly for this application right out of the factory.



NGK (3951) TR55 V-Power Spark Plug, Pack of 1 Review:


Today, I put these in my 2004 Pontiac GTO. They actually fit, despite Amazon's claim that they don't. I conducted my homework and am familiar with the GM LS1 platform, which is used in popular vehicles like the LS1-powered Corvettes, Camaros, and GTOs. The GTO has 11 ft lbs of torque specifications. I installed the plugs without any issues. I used wires from ACDelco that completely matched these. Additionally, I examined the gap on the plugs. They were all set to.050, which is acceptable for the GM LS1 engine. Since the copper core in these plugs requires replacement every 30,000 miles.



NGK 7090 G-Power Platinum Spark Plugs BKR5EGP - 6 PCSNEW Review:


in a 2000 Mercedes CLK430 work properly. It can be done, but good luck getting the ones in the back out by the fender wells. Take the driver's side windshield washer tank out. It's simple to do and has a significant impact. Oh, and if the metal spark plug boots are hard to remove, an open end 3/4 inch wrench can be used.
