Current products and qualified applications
The GSparkPlug discovery baseline contains product names, categories, retailer images, VAT-inclusive and VAT-exclusive prices, availability and retailer product IDs. The daily authorised Awin feed supplies current price, availability and outbound tracking links. Neither source provides complete EAN, SKU or description coverage. A vehicle application appears only where an exact NGK product identifier and vehicle model occur on the same manufacturer-catalogue line. Every year, engine code and variant still needs checking.
Archived references are not confirmed fits
Older GSF records retain the supplier reference, brand, title and any vehicle label. Car filters use the supplier’s model words. They do not establish engine, generation or VIN-level compatibility. Different references can describe related or repeated physical parts; counts are not a census of unique interchangeable parts.
How tyre offers are matched
A valid GTIN, matching brand and matching tyre size are required. GTINs are padded to 14 digits for comparison. Product variants still need checking against the complete retailer specification.
Freshness and coverage
Current GSparkPlug and UK tyre feeds are checked daily at 14:15 UTC after the upstream affiliate collection. This is not a live stock service. Product and tyre affiliate actions expire conservatively within 72 hours of the source date. A failed refresh retains the last complete snapshot and does not renew its source date. The included sellers do not represent the whole UK market.
Car data reviewed but not published
Other stored vehicle data includes manufacturer references, MOT statistics and overseas registration aggregates. Those records do not establish individual part fitment. Restricted public projections and unrelated-market data are excluded from this website.
