We can run these in custom batches down to about 500 units if your lab's testing a new formulation—most buyers go with iridium tip for longer service intervals, but we've done nickel for high-volume fleet work where cost per unit matters more than cycle life.
The high-aluminun alloy ceramic body handles thermal shock better than standerd porcelain, and the 11.8V-12.8V ignition voltge means they'll fire cleanly in distributorless systems even when your battery's marginal (check your TDS for cold-start specs).
Lead time is typically 20 working days or so for color-box packging at 400pcs/ctn, but if you need a smaller trial run our company can do 50 pieces in loose bags—just confirm the electrode type you want because the platinum variant has a 2-week backlog.
What it really does is give you consistent spark energy across 1 to 4 cylinders without the misfire issues you'd get from cheaper ceramic insulators that crack under sustained high RPM.
Actually, these aren't great for vintage points-style ignitions—they're designed for modern coil-on-plug systems where the waveform matters more than the gap adjustment.
100% testing means every plug gets a dielectric withstand check before packing, so you won't see the 2% failure rate typical of unbranded imports, and the 12-month manufacturing defects but not carbon fouling from improper heat range selection.
You can choose from nickel, iridium, or platinum electrodes depending on your performance needs and budget. Iridium and platinum offer longer life, while nickel is a reliable, cost-effective option.
We typically require a minimum order of 400 pieces per model, which is one full carton. But if you need a smaller trial batch, just let us know and we can often work something out.
Our spark plugs are TS16949, ISO9001:2000, and CE certified. That means they meet strict quality and safety standards for automotive parts.
Yes, we include a certificate of compliance and can share test reports from our 100% professional testing process. Just request it when placing your order.
They come in individual color boxes, packed 400 pieces per carton. Each plug measures 9.0×3.0×4.0 cm and weighs about 0.2 kg, so shipping is straightforward.
