High Quality Diesel Euro3 Conmmon Rail Fuel Injector Control Valve 282392949 308z621c 9308-621c 28440421 for Delphi
What our readings say: 2 of the 7 reading-days a verdict needs, and none in the last 7 days.
Seller lists it at $28.00 — a claimed saving of $12.04. AliExpress does not verify that figure, and 5.7% of the listings we track make a claim in the same 40-49% range, so on its own it means very little.

How this compares to everything else we track
We show 23,601 products, one per title, in Automotive. At $15.96, it sits above the middle of that category, which is $15.14 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 43% off. Only 8,617 of the products we track claim a discount that large — 5.7% of the catalogue sits in the 40-49% band, so this one stands out. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.
AliExpress reports 2 orders for it. For comparison, the median listing we track in Automotive reports 8 — though a category holds very different kinds of thing, so read that as scale rather than as a ranking. Order counts come from AliExpress and are not a claim about price.
We have recorded this product’s price on 2 separate days since 2026-10-30, and it has moved 1 time in that window. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.
If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
