Product Details
Part No. 3686
Warranty Details (60 DAY REPLACEMENT IF DEFECTIVE)
NGK V-Power spark plugs offer reliable performance and improved ignitability over standard nickel plugs. Engineered specifically for OE applications, the special V-cut nickel alloy center electrode and concave ground electrode of NGK's V-Power spark plug increases ignitability providing quicker starts and smoother idle. NGK's legendary high grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance. Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties.

Product Features:
  • ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction nickel alloy center electrode with V-groove provides consistent performance
  • RECOMMENDED USAGE: Best for vehicles with OE nickel alloy plugs, not recommended on vehicles with factory precious metal plugs
  • NGK's OE CERAMIC TECHNOLOGY: High grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance
  • SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
  • COLD-ROLLED THREADS: Prevents cross-threading and damage to cylinder heads
  • TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
  • Enhanced Ignitability: The V-cut nickel alloy center electrode and concave ground electrode design of NGK V-Power spark plugs provide quicker starts and smoother idle.
  • OE Application Specific: Engineered specifically for Original Equipment (OE) applications, ensuring compatibility and optimal performance.
  • V-Groove Tip Design: The unique V-Groove tip design of the FR45 model enhances ignitability and overall engine efficiency.

BEST SPARK & GAS MILEAGE
I use these plugs on my everday family van (07 Chrysler Town & Country Touring). I have compared this plug with that of E3 Spark Plugs. The E3's work as advertised but only for a certain period of time before they give out and start giving you problems and unless you know how a car works or performans and notice that it's a faulty spark plug you will not stop to think that it is the spark plug. The E3's caused several different new cars from Suzuki, Ford and Chrysler to hesitate or not fire correctly or at all and that is properly installed. Stick with NGK V-Power. They give you no problems, the same if not better performance and two times cheaper than the E3's.

Wouldn't buy again
I have grand caravan 2001 and got these spark plugs & wires too! They made my car worst off then my original champion that came factory.. that haven't replaced for 18 yr... my car has 176,000 miles.. the gas mileage got worst , it was misfires ect....I hoping to like them since when I purchased them they had limited lifetime warranty .. so now Having to exchange them ....but I will go back to champions as the original OEM, and pay the difference.. sometimes when u go cheaply u get what u pay for.. but bcz of warranty , I took a chance... plus now online it shows 60 warranty compare to when purchase them under the lifetime.. was shocked why they changed warranty? 🤔. .. I did talk to associate and dealership they said bcz they Ngk I bought was low end it has Nickel alloy and copper in them, said I needed the double platts or Iridium spark Plugs.. So thank God it under warranty, so other reviews on other dodges like mine.. you lucky they work for you..

I just wrote a review of the Denso Iridium plugs. Got a misfire with those at 69,000. Luckily I kept my old original NGK plugs, and replaced the offending plug till I could go get a whole new set of NGKs.
Bottom Line Yes, I would recommend to a friend
