Custom Ignition Lead Boxes

Sizing Ignition Lead Boxes Correctly

Lay out your longest set exactly as it will be packed, with the boots and terminals in position, then measure the overall length, width and thickness at the bulkiest point. Boots are the widest part, so check that two boots side by side do not clash, and follow the guide to measuring your product for the clearance to add. Add a few millimetres all round so packers can drop the set in without forcing it.

If you sell sets for four, six and eight cylinder engines, consider whether one box can cover two of those with a different insert. Fewer box sizes simplifies ordering and keeps your print costs down. We will suggest a size range once we know your lead lengths and how many variants you carry.

For coiled sets, the inside diameter of the coil matters: coiling silicone leads too tightly can leave a permanent curl. A gentle coil of 150 mm or more is a safe starting point for most cables.

Printing Part Data Without Clutter

Parts packaging has a lot of information to carry, and it is easy to end up with a box that looks like a spreadsheet. A good layout puts your brand and the product type large on the face, with the part number in bold on both end panels so it reads when the box is stacked spine-out. Fitment data, cylinder count and lead diameter go on the back panel, with a barcode placed where a scanner can reach it on a shelf.

If you sell into several vehicle makes, keep a blank or light panel where a printed label can be applied for each variant. That way one printed box design covers many part numbers, and you only print labels as you need them. Full colour print suits photographs of the leads and engine bay imagery; two-colour print on kraft gives a clean, workshop look for trade ranges.

Board Choices for Parts Shelves and Parcels

Most lead set boxes are made from folding boxboard, which is stiff enough for a light product and takes print well. For heavy-gauge race leads or sets shipped individually by courier, E-flute corrugated adds crush strength and protects the boots if a parcel is dropped; the board and card types guide compares the two. Kraft-backed board hides scuffs better in a busy stores area.

A matt or gloss varnish helps the print shrug off oily fingerprints, which is worth considering for anything handled in a workshop. If the box will sit in a garage for months before fitting, a varnished finish also keeps the part number legible.

Think about how the box opens, too. A tuck-end that a mechanic can open with one hand, without tearing, means the box can be closed again if the wrong set was picked and returned to stock in a saleable state. A tear strip looks tidy but makes resale harder, so most parts brands avoid it for leads. If you sell through a marketplace that measures packaging, check its size limits for your product category before fixing your dimensions.

Who Orders Ignition Lead Packaging

Performance and tuning brands selling silicone lead sets are the most frequent buyers, followed by aftermarket distributors who repack bulk leads under their own label. Classic car specialists use them for reproduction lead kits, and motorcycle parts sellers order shorter versions for twin and four-cylinder bikes alongside their motorcycle parts boxes.

Online sellers who previously shipped leads in a plain bag often switch to a printed box once they start getting marketplace feedback, because a proper box protects the product and makes it feel like a branded part rather than a loose item. Workshop suppliers also use the boxes for service kits that bundle leads with plugs.

Lay the Longest Set Out in Firing Order Before We Draw the Carton

A lead set box is drawn from the longest set in the range, laid out exactly as the installer should find it. Arrange the leads in cylinder order with the boots and terminals in position, measure the overall length, the width across the widest pair of boots and the thickness at the bulkiest point, and photograph the layout beside a ruler. If long race sets are coiled instead, measure the coil. Decide whether the carton hangs on a peg, sits on a shelf or goes straight into a parcel, since the last calls for E-flute rather than boxboard.

Send those dimensions, the number of variants and any logo and part data for printing, and a custom quote comes back by email within one working day, minimums low and quoted per job. A free design proof on the dieline lets you check part numbers and barcodes before anything prints. Production takes 4 to 7 working days after approval and free tracked delivery reaches UK mainland addresses in 2 to 3 working days. Distributors who repack coils and sensors too usually add the general automotive parts boxes in the same artwork.
