The aFe 46-38012B black Silver Bullet spacer is for the exact 2.0L M20A Toyota Corolla and Lexus UX200 applications documented below. Three mounting bolts and an O-ring seal distinguish this kit from the four-bolt Toyota spacers.
| Years / source scope | Model | Exact requirements |
|---|---|---|
| 2019–2026 current page; manual through 2024 | Toyota Corolla | 2.0L M20A application only; actual body/engine must match |
| 2019–2021 exact manual | Lexus UX200 | 2.0L M20A; not UX250h or other Lexus models |
46-38012B: The current Corolla page reaches 2026, but the linked manual ends at 2024 and additionally names UX200 2019–2021. Toyota documents the 2019 Corolla Hatchback's 2.0L M20A engine; a shared SE/XSE label does not certify every sedan, hatchback, hybrid or later configuration. Existing 2019–2021 named Corolla search rows are retained as engine/body-conditional holds, not full fitment passes. Broader later Corolla search mapping remains held pending exact engine/body/trim proof. The exact-manual UX200 application is added without inferring other M20A-powered vehicles.

aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
A model- and engine-specific Silver Bullet throttle-body spacer, not a complete intake or replacement throttle body.
Does it include a filter or coupling?The exact parts list below governs. Generic manufacturer page fields do not establish a supplied intake filter or coupling for this spacer.
Are gains guaranteed?No. Turbulence, throttle-response and whistle statements are manufacturer design claims, not guaranteed horsepower, fuel-economy or sound results for the actual engine.
Which sealing parts are used?Fit the supplied -144 O-ring into the spacer groove and retain the original manifold O-ring. No separate flat gasket is listed.
What is the correct torque?This exact manual does not publish a numeric torque. Obtain the applicable factory/manufacturer tightening requirement; do not borrow a value from a different spacer.
Are all original search rows certified?The current Corolla page reaches 2026, but the linked manual ends at 2024 and additionally names UX200 2019–2021. Toyota documents the 2019 Corolla Hatchback's 2.0L M20A engine; a shared SE/XSE label does not certify every sedan, hatchback, hybrid or later configuration. Existing 2019–2021 named Corolla search rows are retained as engine/body-conditional holds, not full fitment passes. Broader later Corolla search mapping remains held pending exact engine/body/trim proof. The exact-manual UX200 application is added without inferring other M20A-powered vehicles.
Can another spacer’s instructions be substituted?No. Gaskets, O-rings, brackets, screw sizes, control cables and intake restrictions differ by exact part number.
Does the EO reference cover every application?The manufacturer states this product is not CARB exempt and is unavailable for purchase in California or use on vehicles registered with the California DMV.
46-38012B: installation details and any unresolved source scope must be matched to the actual vehicle before use.
