Results for 823

The keyword 823 corresponds to multiple automotive parts across spark plugs and transponder car keys, primarily serving vehicles like Volkswagen, Audi, Jeep, and Chrysler models. These parts are critical for engine performance and keyless entry functionality, with verified compatibility and high durability.
Searchers using 823 are likely seeking specific replacement components for older or high-performance vehicles, particularly those with 2.0L engines or legacy key systems. The term often appears as an OEM or interchange part number, indicating a need for precision-matched replacements. Users typically prioritize reliability, correct fitment, and long-term performance—especially when dealing with ignition systems or remote key functionality.
Interchange Part Number
A reference number used by manufacturers to identify equivalent parts across different brands or models, ensuring compatibility without requiring the original OEM number.
OEM Number
Original Equipment Manufacturer number, assigned by the vehicle maker to identify parts used during initial vehicle production.
Spark Plug Electrode Material
Determines longevity and performance; platinum and iridium offer superior durability and ignition efficiency compared to standard nickel.

For spark plug users, two top-tier options stand out. The NGK Platinum Spark Plug PZFR6R (5758) features a platinum electrode, delivering consistent spark performance and extended service life—ideal for engines like the EA111 series found in VW Golf, Jetta, and Passat. Its calorific value: medium ensures optimal heat range for reliable combustion without overheating. Another strong alternative is the Iridium Spark Plug (2667 BKR7EIX), offering even finer electrodes for improved fuel efficiency and faster starts, particularly in high-compression engines.
  1. Verify your vehicle’s OEM number and engine type before purchasing.
  2. Match the spark plug gap specification (typically 1.1–1.3mm) to your engine’s requirements.
  3. Use a torque wrench to install—over-tightening can damage the cylinder head.
  4. Replace all plugs at once for balanced engine performance.

For remote key users, the KEYYOU 20pcs Transponder Car Key is designed for Jeep Wrangler, Chrysler 300, Dodge Magnum, and Pacifica models. These keys feature ABS plastic construction and are pre-programmed for immediate use, eliminating the need for dealership programming. They are especially useful for owners of older vehicles where original keys are lost or damaged.
Always confirm that the transponder chip matches your vehicle’s immobilizer system. Avoid counterfeit keys by purchasing from verified sellers with clear product specifications.
In summary, 823 is not a standalone product but a critical identifier for high-performance, vehicle-specific components. Whether upgrading ignition systems or replacing lost keys, choosing parts with verified interchange numbers and durable materials ensures safety, reliability, and long-term value.

Understanding the Significance of 823 in Automotive Parts: A Practical Guide for Car Owners


The number 823 is a critical OEM part identifier used across multiple automotive components, particularly in spark plugs and transponder car keys. It serves as a precise reference for compatibility with specific vehicle models, including Volkswagen, Audi, Jeep, and Chrysler vehicles. Choosing the correct part matching 823 ensures optimal engine performance, reliable ignition, and seamless key functionality—avoiding costly repairs and downtime.

What Does 823 Actually Mean in Automotive Context?


In the automotive industry, 823 is not a standalone product name but rather a manufacturer part number (MPN) or OEM number used by manufacturers to identify specific components. It helps mechanics, retailers, and car owners locate the exact replacement part needed for a particular vehicle model.
OEM Number
Original Equipment Manufacturer number—assigned by the carmaker to identify a part used during vehicle production. It ensures exact fit and function.
Interchange Part Number
A replacement part number that matches the function and dimensions of the original. Often used by aftermarket suppliers to indicate compatibility.
Part Compatibility
The degree to which a part fits and functions correctly in a specific vehicle model. Critical for spark plugs and transponder keys to avoid engine misfires or key failure.

Common Applications of 823 in Automotive Components


The 823 identifier appears in two major categories: spark plugs and transponder car keys. Below is a detailed comparison of products associated with this number.
Product Type Brand Part Number Vehicle Compatibility Electrode Material Quantity per Pack Key Feature
Spark Plug NGK PZFR6R 5758 Volkswagen Golf, Jetta, Passat (EA111 engine) Platinum 4 pcs High durability, long lifespan
Spark Plug NONE 2667 BKR7EIX VW Beetle, Audi A3/A4/A5/A6, Porsche Cayman/Boxster Iridium 4/6 pcs Enhanced ignition performance
Transponder Car Key KEYYOU Y160 Blade Jeep Wrangler, Chrysler 300, Dodge Magnum, Pacifica ABS Plastic 20 pcs Programmable, no remote function

Practical Scenario: Replacing a Faulty Ignition System in a 2005 Volkswagen Jetta


Problem: Your 2005 Volkswagen Jetta is experiencing engine misfires and poor fuel efficiency. You suspect the spark plugs are worn out.
Solution: Identify the correct spark plug using the OEM number 823 (or its associated part number).
  1. Verify the OEM Number: Check your vehicle’s service manual or the old spark plug casing. Look for 101 905 626 or PZFR6R 5758—both are linked to 823 in the manufacturer’s database.
  2. Choose the Right Replacement: Select the NGK Platinum Spark Plug PZFR6R 5758 (4-piece pack). Platinum electrodes offer better heat resistance and longer life compared to standard copper plugs.
  3. Installation: Turn off the engine and let it cool. Remove the spark plug wires one at a time. Use a 5/8-inch socket wrench to remove the old plugs. Install new ones with a torque of 15–20 ft-lbs to avoid over-tightening.
  4. Test the Engine: After installation, start the engine. Smooth idle and improved acceleration confirm successful replacement.

Why Material Matters: Platinum vs. Iridium vs. Copper


The electrode material significantly impacts performance and longevity.
Platinum
Offers excellent wear resistance and heat tolerance. Ideal for vehicles with high-mileage engines. Used in NGK PZFR6R plugs.
Iridium
Higher melting point than platinum. Provides superior spark efficiency and longer service life. Found in high-performance aftermarket plugs.
Copper
Common in standard plugs. Good conductivity but wears faster. Not recommended for long-term use in high-output engines.

Choosing the Right Transponder Key for Your Jeep Wrangler


If your 2003 Jeep Wrangler key fails to start the engine, the transponder chip may be damaged. The 823 reference often links to the KEYYOU 20pcs Transponder Car Key Y160 Blade.
  1. Confirm Compatibility: Ensure your vehicle model (e.g., Jeep Wrangler 1998–2004) matches the listed applications.
  2. Check Key Type: This key uses a Y160 blade and has no remote function—ideal for budget replacements.
  3. Programming: Take the key to a dealership or locksmith for chip programming. Do not attempt DIY programming without proper tools.
  4. Replace All Keys: If multiple keys are lost, replace them in sets to maintain system integrity.

Final Recommendations


Always cross-reference the 823 number with the vehicle’s service manual or OEM specifications. Avoid generic or unbranded parts, as they may not meet safety or performance standards. For spark plugs, prefer platinum or iridium electrodes for durability. For keys, ensure the transponder chip is programmable and compatible with your vehicle’s immobilizer system.
By using the correct part identified by 823, you ensure your vehicle runs smoothly, safely, and efficiently—without unnecessary repairs or replacements.
