Parts & fitment · manufacturer evidence

Original plug, Honda reference and NGK RX alternative

NGK's launch bulletin supplies a documented aftermarket option as well as the original-specification plug reference. Keep the product name, stock number and Honda reference separate so the seller's invoice identifies what you are actually buying.

Documented period: NGK August 2021 bulletin NR21-006: Vezel RU3/RU4 hybrid LEB, December 2013 onward as printed. This dated application is not a current Honda supersession list.

Buyer context: Pakistan / Bangladesh / Kenya. The evidence remains Japan-market application data; destination-country stock and local factory fitment are not established.

RU3 · product identity, evidence status and buyer decision
Identifier / proposalEvidence status and scopeBefore purchase
NGK LKAR7BRX11PS / stock 97544Manufacturer-listed application

The bulletin announces this Premium RX product and includes the RU3/RU4 LEB application; the row specifies four plugs.

If buying RX, ask for both identifiers and quantity four. Do not confuse stock 97544 with a Honda ordering number or claim it is the factory-fitted model.
DILZKAR7C11S / Honda 12290-5R0-003OEM cross-reference in supplier catalog

NGK's RU3/RU4 row prints the original plug model and this Honda genuine-number reference.

For an original-specification or Honda genuine order, make the proposed product explicit and ask Honda to resolve current chassis-specific supersessions.
Any similar iridium plug, coil or current supersessionNot established here

The source does not make lookalike codes equivalent, identify ignition coils, diagnose rough running or establish a current genuine replacement chain.

Require a separate exact manufacturer application for another product. A seller's engine-name match alone is insufficient.
  • Copy the full code including every suffix. Ask whether the offer is a single plug or a set, and retain the package identifiers and invoice.
  • The bulletin's 2021 launch price is not a present retail or landed-price benchmark and is deliberately not used here. Obtain a written current quote including delivery and return conditions.
  • Fitment evidence does not establish a maintenance interval, installation torque or cause of a warning light. Use the exact vehicle's service information and qualified diagnosis for those questions.
  • For Pakistan, Bangladesh or Kenya, compare quotations for the same named product and condition; country context does not establish local availability or a supplier partnership.

Step-by-step instructions

Choose the correct manufacturer-backed specification

Use these source-backed checks to identify the option for your exact equipment. This is a selection guide, not a hands-on replacement procedure. If a component or label looks different on your car, stop and check your own manual.

  1. Step 1 of 5

    Match RU3 and the LEB engine before using the row

    NGK's manufacturer bulletin separates Vezel RU3/RU4 hybrid LEB from other Honda engine rows. Its RU3/RU4 row starts at December 2013. Confirm the exact vehicle and production record rather than selecting a plug from the Vezel badge or a photograph of a similar box. A shared seller category is not fitment evidence.

    All steps ↑
  2. Step 2 of 5

    Keep three identifiers separate on the order

    The cited row lists original plug DILZKAR7C11S, Honda reference 12290-5R0-003, and quantity four. The alphanumeric plug model, vehicle-maker reference and number of plugs answer different questions. Ask the seller to print the complete proposed product code on the invoice; a generic four-pack described as iridium is insufficient.

    All steps ↑
  3. Step 3 of 5

    Check whether the offer is original specification or an alternative

    The bulletin also concerns an RX product launch. A proposed alternative needs the manufacturer's actual application row and any exclusions; do not infer equivalence from thread size, appearance or a similar suffix. A later OEM supersession must be confirmed against the chassis by Honda. This page does not establish that an old reference remains the current ordering number.

    All steps ↑
  4. Step 4 of 5

    Separate a maintenance order from a fault diagnosis

    Ask why plugs are proposed: documented scheduled work, an observed wear finding or a diagnostic conclusion. An engine warning or rough running does not by itself prove that plugs are the cause. Request the relevant findings before buying coils or additional ignition parts. The cited fitment row supplies neither a replacement interval nor a workshop torque.

    All steps ↑
  5. Step 5 of 5

    Make the purchase traceable

    Keep the manufacturer cross-reference, exact ordered code, quantity, seller identity and return terms together. Resolve a different installed marking rather than copying it blindly: a previous owner may have fitted an unsuitable part. If the source row, engine identity or proposed supersession disagrees, pause the order and obtain written clarification.
