Features & Details

  • Ideal for Routine Maintenance
  • Improves Spark Energy for More Power
  • Set of 8 NGK V-Power Performance Spark Plugs
  • Set of 8 Taylor Street Thunder 8mm Spark Plug Wires
  • Taylor Red Replacement Cap & Rotor Kit

Regular Maintenance. Replacing your old weak spark plugs, wires and cap & rotor is paramount to keep your engine running smoothly and efficiently, so replace them all at the same time with this convenient tune-up kit from OPR.

Kit Includes. This ignition tune-up kit includes Taylor Street Thunder 8mm Spark Plug Wires, Replacement Cap & Rotor Kit and a set of NGK V-Power Performance Spark Plugs.

V-Power. NGK V-Power Performance Spark Plugs feature a copper core for its superior conductivity and a durable nickel alloy tip to assure a strong spark to keep your 'Stang running at it's peak efficiency. The V-Power plug has a unique V-Groove that allows the spark to happen at the edge of the center electrode, so that the heat is not absorbed by the electrode itself, resulting in a complete efficient burn.

8mm Spark Plug Wires. Taylor uses a Kevlar helically spiral wound core conductor that provides greater suppression of Electro Magnetic (EMI) and Radio Frequency Interference (RFI) to shield your vehicles sensitive electronics. These Street Thunder Spark Plug Wires also feature a low resistance of only 500 ohms per 12 inches of wire to produce greater spark energy, and improve power, idle, and fuel efficiency.

Cap and Rotor. Taylor's Distributor Cap and Rotor is injection molded from an alkyd compound that provides superior protection against cross firing and arcing. The corrosion resistant brass inserts and steel rotor springs provide high conductivity and unrestricted energy flow for a hotter spark.

Application. This OPR Ignition Tune-Up Kit is specifically designed as a direct fit replacement upgrade for the 1989-1993 Mustangs equipped with the 5.0L V8 engine, including the LX 5.0, GT, and SVT Cobra models.

      are the spark plugs in this kit pre gap or do i need to gap them Brought this kit was wonder if spark plugs are pre gap

      • They come pre-gapped; however, it is always highly recommended to check the gap on any spark plugs prior to installation to check for accuracy.

          mustang 5.0 lx

          Great item and great price-my mechaninc wanted to book me 275 for tune up-I spent 65 and did it myself-took 1 hour had trouble with plug #4. I received the 8 wires plus 1 for the top of the cap/roter-there is also a smaller 1 about 8 to 10 inches-what is this for?

          This kit did a fantastic job of refreshing my cars idle and throttle response. Spark plugs did not work for me because I was not thinking about having aluminum heads but the cap rotor and wires made a huge difference.

          Everything is so smooth now.

          Installed this kit last week. I immediately noticed how smooth the idle was when I started it, and the throttle response was seriously so much improved. The car no longer hesitates to move when you give it any gas. The only reason I'm not giving it 5 stars is that for whatever reason the wires aren't very tight on the cap and they seem to slowly be pushing themselves off, so every now and then I have to push them back down toward the cap. Other than that I'm overall very happy, extremely good value for what you get.

          Purrs like a cat looks like a Pony

          I was at our local mechanic and inquired about the price of a tune up on my slowly tiring 5.0 Foxbody and in seconds the answer..$254.00. Knowing that labor goes for about $90.00 an hour I said thanks and cracked open my latest edition of American Muscle Catalog. After receiving the kit ($64.00 and free shipping) I did the work myself after watching two videos from ...yeah you guessed it American Muscle set the timing and Voila! Great products Great service Great advice for an old school guy who likes to keep it "stock" Thanxz AM

          The car needed a much needed tune up and this is a amazing tune up kit it's cheap, restores performance, and cleans the engine bay up great. I highly recommend this tune up kit if you wanna get new plugs, wires, cap and rotor. Made mine performe better, look better, and improved my mileage.

          Great Products

          Got this shipped to Canada with no hassles. My mustang had a miss so I ordered up this kit and it's not running better then ever. Great quality products and the speak plugs were already gapped properly. If your mustang needs a little spark brough back into its life this kits for you.

          Very impressed!

          I bought this kit for my 93 mustang Bc I had a terrible misfire above 3000 rpm that sounded like an assault rifle. So I bought this tune up kit after doing my cheapskate research. Install was great only took a little over an hour Bc some of my old boots were hard to reach and come off, and one other great thing was I the plugs are pregapped and I only had to regap one!

          Really good deal.

          After getting tune up quotes ranging from $375-$450 I decided to do this myself. The product arrived quickly and was just as described/pictured. I was a little worried at first because the distributor cap didn't have a marking for the #1 plug but it didn't really matter because the cap only fit one way (same position as the old one). Everything took me about 3 hours, mainly because removing some of my old plugs was tough (especially #3 and #4). However, I had no problems installing the new plugs and wires. The engine bay looks much better and I expect the car to run a little better too. Great value!

          Great bang for your buck.

          My 89 5.0 was running rough and eventually had a misfire. The mechanic quoted me at almost $500 to replace plugs, wires, cap and rotor. I did this myself in a couple of hours with minimal mechanical ability. The car has never run better. Cheap and easy fix for such a dramatic improvement. Plugs came pre-gapped but make sure they are all to the car's specifications. Don't forget dielectric grease!
