The IX-suffix and DILFR/IFR/IL codes
This page collects two code groups from the spark plug catalogue: the IX-suffix codes and the codes under the DILFR, IFR and IL prefixes. Eleven detailed listings carry these codes, each titled with its vehicle applications and printed with cross references.

Reading the codes
The groups on this page are code groups, read off the type codes themselves: an IX inside the code — BKR5EIX11, DCPR8EIX — places a listing in the IX-suffix group, and the DILFR, IFR and IL prefixes place a listing in the second group. The standard and copper-core codes sit on the copper spark plugs page, and the full 28-reference range is on the spark plugs category page. The blog article iridium vs copper spark plugs sets the code groups side by side as the listings present them.
Specifications as listed
The detailed listings print the thread diameter — M14 x 1.25 on the BKR5EIX11 listing — and they print the construction: "Nickel alloy, Copper core center electrode." That construction line appears on these codes' listings just as it does across the range — on BCPR6EIX, BKR5EIX11 and the DILFR/IFR/IL listings alike. This page therefore presents the two groups by their codes, applications and cross references, and gives the construction exactly as the listings print it.
Ordering from this page's range
A wholesaler stocking for the vehicles in the table orders by the code in the listing; the cross references on the listings (FR8DP and IK16 against BKR5EIX11, for example) connect the code to the other number systems a workshop may carry.
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 spark plug 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.
Codes that are not on this page
The rest of the plug range sits elsewhere: the copper-core standards on the copper spark plugs page, and two listings that serve smaller engines — C7HSA, listed for Agility, Kisbee and Tweet scooters, and D8EA, listed for CB, CG and CL applications — inside the full 28-reference table on the spark plugs page. If the code in front of you carries no IX and no DILFR/IFR/IL prefix, it belongs to one of those pages.
