Review TOYOTA Oem Blacktop Itb Intake Funnels Stacks fits 4AGE

The **Toyota 17113-16020 AE111 4-Age Blacktop Intake Funnel Stack** is a meticulously engineered aftermarket performance component designed to enhance the breathing and efficiency of Toyota engines equipped with the **AE111** (or similar) intake manifold, commonly found in models like the **Toyota 4Runner, Tundra, Tacoma, and Land Cruiser** from the late 1990s through the early 2000s. Crafted from high-quality **blacktop (black-painted aluminum)**, this intake funnel stack is built to replace the stock plastic or painted intake components, offering a sleeker, more aggressive aesthetic while significantly improving airflow dynamics. The **4-Age design** refers to its compatibility with four distinct throttle body configurations, ensuring broad applicability across various engine variants, including naturally aspirated and mild turbocharged applications. Each funnel is precision-machined to maintain optimal airflow velocity, reducing turbulence and vacuum restrictions that can hinder throttle response and horsepower potential. The **smooth, tapered contours** of the intake funnels are engineered to minimize restriction while maximizing the velocity of incoming air, allowing for better fuel atomization and combustion efficiency. This stack is particularly well-suited for applications where stock intake components have become restrictive, such as in high-performance builds, forced induction setups, or when upgrading to larger throttle bodies. The **blacktop finish** not only provides a polished, high-end look but also offers better heat dissipation compared to painted aluminum, helping to maintain consistent airflow performance under demanding conditions. Whether paired with a cold air intake, performance throttle body, or as part of a full intake manifold upgrade, this funnel stack is a straightforward yet impactful modification that delivers measurable gains in power, responsiveness, and overall drivability. Built to withstand the rigors of daily driving and spirited performance use, it is a reliable choice for enthusiasts seeking a balance of aesthetics and functionality in their Toyota s intake system.

**Pros and Cons of buying a Toyota 17113-16020 (AE111 4-Age Blacktop ITB Intake Funnels Stack)**

1. **Performance Enhancement** These intake funnels are designed to improve airflow into the engine, which can lead to better throttle response, increased horsepower, and smoother acceleration. They are often used in tuning applications to complement other modifications like ECU tuning or exhaust upgrades.

2. **OEM Fitment** As a genuine or high-quality aftermarket part for the AE111 engine (common in early 4th-gen 4Runner, Tundra, and Sequoia models), they should fit without major modifications, reducing installation hassle.

3. **Durability** Blacktop-coated funnels are resistant to corrosion and wear, making them suitable for off-road or rugged use where debris and moisture are common.

4. **Compatibility with ITB (Intake Tube Bypass)** These funnels are specifically designed for ITB setups, which can help reduce intake restriction and improve airflow dynamics, especially when paired with a performance air filter.

5. **Aesthetic Appeal** The blacktop finish gives a clean, polished look to the intake system, enhancing the vehicle s appearance if it s part of a tuning or cosmetic upgrade.

6. **Potential for Increased MPG (with Tuning)** While stock, these funnels alone won t improve fuel efficiency, but when paired with an ECU tune, they can optimize airflow for better combustion efficiency in some cases.

7. **Easy Installation** Many aftermarket versions of these funnels are designed for straightforward bolt-on installation, requiring minimal tools and time.

1. **Minimal Power Gain Without Tuning** These funnels alone will not significantly increase horsepower or torque. For noticeable performance improvements, they must be paired with an ECU tune or other supporting modifications (e.g., exhaust, fuel system upgrades).

2. **Cost** While not excessively expensive, the price may be a concern for budget-conscious buyers, especially if additional modifications (like a tune) are needed to realize performance benefits.

3. **Potential for Voiding Warranty** Installing aftermarket intake parts may void the vehicle s factory warranty, particularly if the manufacturer considers it a non-OEM modification.

4. **Compatibility Issues** If the funnels are not perfectly matched to the vehicle s specific year or trim, there could be fitment problems, such as gaps or interference with surrounding components.

5. **Maintenance Requirements** Off-road use or exposure to dirt and moisture may require occasional cleaning or inspection to prevent clogging or corrosion, especially in the blacktop coating.

6. **Limited Sound Changes** Unlike exhaust modifications, these funnels do not produce a noticeable exhaust note; their primary benefit is airflow rather than audio.

7. **Market Availability** Depending on the region, these parts may not be widely stocked, requiring online purchases or specialty suppliers, which could delay installation.

The **Toyota 17113-16020 (AE111 4-Age Blacktop ITB Intake Funnels Stack)** is a practical choice for enthusiasts looking to enhance airflow into their engine as part of a broader tuning project. They offer tangible benefits in performance when combined with an ECU tune or other supporting modifications, while also providing durability and aesthetic improvements. However, they are not a standalone "power upgrade" and require additional work to unlock their full potential. The decision to purchase should be based on whether you are planning a full tuning package or simply seeking a cosmetic/intake upgrade.

---

- You are already planning or have completed other performance modifications (e.g., ECU tune, exhaust, fuel system upgrades).

- You want to improve airflow for better throttle response and potential horsepower gains.

- You appreciate the blacktop finish for a cleaner look and corrosion resistance.

- You are comfortable with bolt-on modifications and understand the need for supporting upgrades.

- You are looking for a quick, standalone power increase without additional tuning.

- You prioritize cost efficiency over performance enhancements.

- You are concerned about warranty implications or prefer to stick with stock components.

- You cannot source the part easily or are unsure about fitment.

**Final Verdict:** This intake funnel stack is a solid addition for tuned AE111 engines, but it should be part of a larger performance plan rather than a solo purchase. If you re serious about improving your vehicle s performance, pair it with a reputable ECU tune and monitor results. For casual drivers or those not pursuing performance upgrades, the benefits may not justify the cost.
