What our readings say: Has been $116.00 within 10 days.
Seller lists it at $444.00 — a claimed saving of $88.80. AliExpress does not verify that figure, and 11.4% of the listings we track make a claim in the same under 30% range, so on its own it means very little.

Rotor Head X4, 4 Cylinder, Pump Head 129602-51741, Head Rotor, 4TNV88/4D88, for Yanmar. Diesel Fuel Engine Injection System Part — listed under Automotive. Full specifications are on the AliExpress product page.
We track 12,605 products in Automotive. At $355.20, it sits above the middle of that category, which is $16.38 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 20% off. That is modest for this catalogue, where 9,327 products (11.4%) sit in the same under 30% band and most of the rest claim far more. A small claim is at least a plausible one. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.
AliExpress reports 6 orders for it. For comparison, the median listing we track in Automotive reports 9 — 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 13 separate days since 2026-08-30, and it has moved 7 times 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.
All under $355.20 with at least 100 reported orders.
