Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high-performance engines. Trivalent metal plating has superior anti-corrosion and anti-seizing properties. Review: Perfect! - I purchased these for my 'baby', my '04 Volvo XC90. Engine runs smooth. I feel very safe, knowing I've got the best plugs & that I've done everything in my power to care for the safety of my family. Reliability means everything in Alaska. For the safety of my family, the engine must start quickly every time, and must run like new. The smooth starts and efficient plug firing also provides the best fuel economy. You can't beat NGK quality and you can't beat iridium electrodes. I'm 62 years old and have tuned up my fair share of engines. I am very impressed with these plugs, their obvious quality and because they make my engine run like brand new. I recommend these plugs. Review: One fine spark plug. - The Japanese car we scoot around in started idling rough and lost power. I recognized the syndrome. Time for a spark plug change. The car came with NGKs, and I'm happy to continue using them. Over the years I've seen many spark plug designs and features come and go. I passed up the split, forked or otherwise as well as the old fashioned copper core spark plugs. Iridium seems to be the top plug. These were available with Prime shipping. I ordered and installed them. Whenever I install new spark plugs I make it a habit to also change the spark plug wires. Sure, a little more money and time, but your are right there anyway. Pull off a cap, or scrape the wire, have corrosion on one of the connections and you're hiking down to the auto parts store. Use anti-seize on the threads. This is a must. Put a dollop of tune-up grease on the top of the spark plug and the connections of the spark plug wire. Torque the spark plug to manufacturer's specifications. Do not over torque. Resist the urge. You do not want to twist the top off of the spark plug and have to extract the base. When all was back together the idle was smooth, glass smooth, acceleration was back, the car was happy again. ## Features - Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling - The 0.6mm laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect - Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage - Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high-performance engines ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000A8JLIY | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #600,770 in Automotive ( See Top 100 in Automotive ) #3,427 in Automotive Replacement Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car | | Core Material | Copper | | Customer Reviews | 4.6 out of 5 stars 351 Reviews | | Global Trade Identification Number | 00087295154649 | | Included Components | Per Item Description | | Item Weight | 0.05 Kilograms | | Manufacturer | NGK | | Manufacturer Part Number | BKR5EIX-11 | | Manufacturer Warranty Description | 30 Days | | Model Number | BKR5EIX-11 | | OEM Equivalent Part Number | Cross-reference is for reference only.

I've got power I didn't know it had. **Q: Hi, when you say one pack , it contains how may pieces?** A: Product description says Pack of 1. **Q: Are these pre gapped or do you have to gap them on your own?** A: I never trust "Pre-gapped"; always do your own checking. Better safe than sorry! **Q: what all is needed with these ngk spark plugs besides the ngk wires and what does it mean "gap" between spark plugs?** A: NGK:BKR5EKB-11 ( '11' at the end of the "plug code" stands for 1.1mm (0.044-in) preset gap in the plug required for my vehicle. . I did not say "gap" between plugs. Before installing the spark plug, the gap of the spark plug electrode has to be set according to the requirement of the vehicle. Refer the manual for the required gap in your spark plug for your vehicle. I ordered plug which are preset according the manual, so that it could be installed directly into the vehicle with out adjusting the gap. Gap adjustment is required for the discharge of current evenly for the vehicle to perform well. I hope this clarifies your doubt. . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect! *by A***A on September 29, 2013* I purchased these for my 'baby', my '04 Volvo XC90. Engine runs smooth.
