Copper-core plugs, listed by code
The copper side of the spark plug catalogue is explicit about its construction: the listings describe a nickel alloy plug with a copper core centre electrode. That description is printed on the standard-code listings — BCP5ES-11, BKR5ES11 and the rest of the BKR/BCP/BP families set out below.

What the listings specify
Thread diameter is printed as M14 x 1.25 on the BCP5ES-11 and BKR5ES11 listings. The construction line — nickel alloy, copper core centre electrode — is the listings' own description of these plugs. Function is stated in one line on the listings: to ignite the air-fuel mixture in the engine's combustion chamber by generating an electric spark. The IX-suffix and DILFR/IFR/IL code groups are listed separately on the iridium spark plugs page; the blog comparison iridium vs copper spark plugs covers how buyers choose between the families, and the spark plugs page shows the complete range of 28 references.
Where copper-core plugs sit in an order
The applications in the table span the catalogue's core car parc — Corolla, Camry, Accent, Getz, Avensis, Corona. Both families come from the same listings system, so a mixed plug order — copper-core codes for the applications in this table, IX/DILFR/IFR/IL codes for the applications listed under them — is one enquiry: send the codes and quantities together.
On manufacture, the spark plug listings describe a dedicated production operation: ceramic insulators formed by isostatic pressing, metal parts machined on automatic CNC equipment, assembly on an automatic line, and customised inner boxes, outer boxes and printing available on the parts — the company's own description of its spark plug line.
Ordering facts for this family
- Samples: Free samples are offered.
- Small orders: Accepted on items in stock, per the listings.
- Packaging: Customised inner box, outer box and printing described on the listings.
- Delivery: The company FAQ gives a general delivery figure of 30–40 days. The catalogue's named listings that print a delivery window print 20–45 days according to OE number and quantity; where the listing for your code prints no window, ask for its window in your enquiry.
The BP-code listings
Two listings in the table are the BP codes: BP6ES, listed for Carina, Corolla and Cressida, and BPR6ES, listed for Corona, Crown and Hilux. They sit in the same listings system as every other code in the table — a distributor whose market runs those models orders them by the same route, with no separate list to consult.
Frequently asked questions
Are the copper-core plugs pre-gapped or marked by gap in the catalogue?
The listings identify plugs by type code, thread diameter, application and cross reference; the code itself is the identifier to order by. For any figure a listing does not print, ask against the specific code.
Which copper code fits a Corolla?
Seven listings name the Corolla: BCP5ES-11, BKR5E11, BKR6E, BKR6E11, BKR6EGP, BKR6EZ and BP6ES. The code from the plug being replaced is what separates them — or send the vehicle and engine details.
