What our readings say: Typical across 18 readings: $11.84.

Universal racing Adjustable Manual Turbo Boost Valve Controller Kit 1-30 PSI In-Cabin Booster control — listed under Automotive. Full specifications are on the AliExpress product page.
8 products in Automotive close enough to compare on price — 1 is cheaper than this one.
We track 16,677 products in Automotive. At $11.40, it sits below the middle of that category, which is $16.09 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 5% off. That is modest for this catalogue, where 14,431 products (13.3%) 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 47 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 18 separate days since 2026-08-10, and it has moved 2 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 $11.40 with at least 100 reported orders.
