The engine in a vehicle needs a proper fuel-air mixture and a spark to ignite it. The purpose of the ignition system is to provide the proper spark at the right time allowing the fuel-air mixture to ignite for effective engine performance. If your Infiniti is hard to start or misses under load and idle rough, check your ignition system for worn or damaged parts. If you have found that any of its parts should be replaced, never wait too long until you get stuck in the middle of nowhere. Before you waste your time running out to the auto parts chain store, look through our wide selection of high-quality replacement Infiniti ignition parts to find the product you need.

We carry everything you may need from spark plugs and wires to distributors and coils. Cooperating with leading OE and aftermarket brands, most of which are suppliers to the vehicle manufacturers, we guarantee that the parts you get from us are the same as the original ones. With thousands of high-quality products and dozens of well-known names such as Dorman, Denso, NGK, Autolite, Motorcraft, etc., you will spend a minute or so to find the product you need to return your Infiniti back to the road.

      Since their inception at the start of the 20th century, motor vehicles with gasoline burning engines have needed a precise way to deliver an electrical spark to each of the engine's cylinders. (Note that diesel engines do not rely on an electrical spark to ignite the fuel-air mixture.) For much of the past 100 years, the spark has been delivered by the ignition distributor. The distributor is always mechanically linked or timed to the engine's rotation so that the spark is sent at the exact moment it is needed.

      The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine" because they were made by the exact same production facility that made the parts installed on the assembly line.

      This article will guide you through a generic tune up on most any car or light duty gasoline-powered vehicle built within the last 20 years or so. We will presume that you are tuning up your engine because it has reached the mileage or time point to do so, and that you are NOT performing a tune up to cure an engine performance defect. We make this distinction because not all running/performance issues will be solved via a simple tune up.

      Since the dawn of the automobile, spark plugs have been an integral part of gasoline engines because they conduct the electrical energy from a vehicle’s ignition system needed to finalize the combustion process. After the gas/air mixture has been fully compressed inside the cylinder head, spark plugs serve a miniature bolt of lightning to create an explosion which pushes a piston downward.

    Very Good
    Plug wires are great! Very happy with this product! Installation took no more than 10 minutes, and the effect was quite noticeable! However, I didn't see any improvement of mpg, mostly just throttle response and hp. Overall, a great product, thanks!
