Cold Air Intake for 1996-2005 Chevy S10, Blazer, GMC Jimmy and Sonoma 4.3L V6
This bolt-on cold air intake gives 1996-2005 Chevy S10, Blazer, GMC Jimmy and Sonoma owners a deeper induction note and quicker throttle response from the 4.3L V6, with no cutting or drilling involved. It replaces the factory airbox assembly with an aluminum intake tube and a washable cone filter you rinse and reuse instead of throwing away. Coverage runs across the 1996-2004 Chevy S10 and GMC Sonoma pickups, the 1996-2005 Chevy Blazer, the 1996-2004 GMC Jimmy, the 1996-2001 Oldsmobile Bravada and the 1997-2000 Isuzu Hombre. Installation is a hand-tool job that usually takes about 45-90 minutes. Compare your engine and body style with the fitment list below before you order.

Key Features
- Aluminum intake tubing: the pipe is built from lightweight aluminum, replacing the factory airbox assembly on the applications above.
- High-flow cone filter: the engine draws through a washable cone element instead of a sealed panel-filter box, and the filter is reusable rather than disposable.
- Sharper throttle response: the kit is aimed at low and mid-range response, so the truck feels more willing off idle and through part throttle.
- Deeper induction note: a noticeably deeper intake tone under acceleration than the stock airbox, while cruising stays quiet.
- Expected output range: approximately 7-10% more horsepower and 6-8% more torque; results depend on engine condition, calibration and supporting hardware.
- Bolt-on install: about 45-90 minutes with basic hand tools, and no cutting or permanent modification is required.
- Mounting hardware included: the kit ships with the mounting accessories for the applications above, so no extra brackets are needed.
Who This Kit Is For
This Flashark cold air intake replaces the factory airbox assembly on 1996-2004 Chevy S10 and GMC Sonoma pickups, the 1996-2005 Chevy Blazer, the 1996-2004 GMC Jimmy, the 1996-2001 Oldsmobile Bravada and the 1997-2000 Isuzu Hombre with the 4.3L V6.
For you if you drive one of those 4.3L V6 trucks or SUVs and want a first bolt-on change, you want a deeper induction note and quicker throttle response more than a silent cabin, you prefer a washable and reusable filter over disposable paper elements, you plan to install it yourself with basic hand tools, and you have checked your state emissions rules in the sections below.
Not for you if you need a heat shield or a sealed airbox, since neither is part of this kit, you expect a guaranteed MPG gain, you are in California or another CARB-adopting state and need an EO number, or you regularly ford deep water without relocating the filter.
If you are building the same trucks for more power, pair this intake with S10, Blazer, Sonoma and Jimmy 4.3L V6 headers.

Check Before Ordering
- Vehicle: exact fit for the six applications in the fitment table above, all with the 4.3L V6. If your truck or SUV has a different engine, body or year, message us before ordering.
- Intake type and heat shield: this kit is a cold air intake kit with a cone filter on aluminum tubing. A heat shield and a sealed airbox are not included, so plan for one separately if your build needs thermal isolation.
- Filter: one washable, reusable cone filter is included, and there is no dry-filter version of this SKU. Cleaning keeps it flowing, and dusty or off-road driving means checking it more often.
- Sensors: the kit keeps the factory MAF/IAT sensor in its original position and bore. Compare the sensor and throttle body layout in your engine bay with the kit photos before ordering, and message us if anything looks different.
- Legality: this kit carries no CARB EO number, so it is not legal for sale or use in California and other CARB-adopting states. See the compliance notice at the bottom of the page.
- Install and conditions: bolt-on with basic hand tools in about 45-90 minutes, with no cutting or drilling. Avoid deep water crossings, because water ingestion can cause hydrolock and severe engine damage.
What's in the Box
- 1 x Flashark performance cold air intake for the 4.3L V6 applications above
- Mounting accessories for those applications, as shown in the product listing
Your factory MAF/IAT sensor is reused rather than replaced, and basic hand tools cover the install.

1996-2005 Chevy S10, Blazer, GMC Jimmy and Sonoma 4.3L V6 Cold Air Intake FAQs
Q1: Is this cold air intake legal in my state?
A1: This kit does not carry a CARB EO number, so it is not legal for sale or use in California (and other CARB-adopting states). Other states run their own emissions and inspection rules, so check yours before ordering.
Q2: Will this cold air intake fit my Chevy S10, Blazer, Jimmy or Sonoma?
A2: It is an exact fit for 1996-2004 Chevy S10 and GMC Sonoma, 1996-2005 Chevy Blazer, 1996-2004 GMC Jimmy, 1996-2001 Oldsmobile Bravada and 1997-2000 Isuzu Hombre models with the 4.3L V6. If your truck or SUV is a different year, body style or engine, contact us to verify your YMM before ordering.
Q3: How much horsepower will this add to a 4.3L V6?
A3: Typical intake-only gains for this application are approximately 7-10% horsepower and 6-8% torque. Actual results depend on the vehicle, calibration, installation, and supporting hardware. The change you notice first is usually sharper throttle response.
Q4: Will a cold air intake improve my MPG?
A4: MPG is dominated by driving habits; an intake alone can't guarantee a measurable gain. Expect the main benefit as throttle response and intake tone rather than fuel economy.
Q5: Will this void my warranty?
A5: Under the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless it is proven to have caused the failure. This kit is designed as a direct bolt-on replacement that keeps factory sensors and connections.
Q6: Will it throw a check engine light (CEL)?
A6: This kit is designed to retain the factory MAF/IAT sensor location and bore, which keeps the MAF calibration within the OEM design envelope. CELs are usually the result of an intake leak, an over-oiled filter, or a mismatched sensor bore, and the install checklist covers how to avoid each one. If you already have a rough idle or a code after fitting an intake, the 7-point rough idle after cold air intake installation checklist walks through the usual causes.
Q7: Do I need a tune after installing?
A7: No tune is required for a bolt-on install that retains the factory sensors. If you add headers, a cam or other airflow changes later, a custom tune can make better use of them.
Q8: Is this safe in rain or deep water?
A8: Normal rain driving is fine for an intake that sits inside the engine bay. Avoid deep water crossings, because water ingestion can cause hydrolock and severe engine damage. If you ford water regularly, look at a high-mounted or relocation setup instead.
Q9: How do I clean and re-oil the filter?
A9: This kit ships with one washable, reusable cone filter. Rinse the element clean, let it dry completely, then refit it, and clean it more often if you drive in dusty or off-road conditions. If your filter uses oil, apply it sparingly, because an over-oiled filter can coat the MAF sensor. The step-by-step cold air intake filter cleaning guide shows the full process.
Q10: What does it sound like?
A10: You'll hear a deeper intake tone under acceleration; at cruise it quiets down. Sound is subjective, so if you want the loudest option, an open-element short ram setup is louder than a sealed one.
Q11: What's included, and what do I still need?
A11: The box contains the cold air intake assembly and the mounting accessories for the applications above. Your factory MAF/IAT sensor is reused rather than replaced, basic hand tools are all you need, and a heat shield or sealed airbox is not part of this kit, so plan for one separately if your build needs thermal isolation.
Q12: Does it work with both CPI and Vortec 4.3L engines?
A12: It covers the 4.3L V6 used in these trucks and SUVs, including CPI and Vortec versions, as long as the intake routing and sensor layout match the kit design. Compare your engine bay with the kit before you start.
Q13: Is this intake good for towing and light off-road use?
A13: Yes, it can be used for towing and light off-road driving. In dusty conditions, check and clean the filter more often so it keeps flowing and keeps protecting the engine.
Q14: What's the difference between this intake and the stock airbox?
A14: The stock airbox is built for quiet operation and stable filtration. This kit replaces it with a cone filter and aluminum tubing, which reduces intake restriction and changes the induction note and throttle feel; the trade-off is more noise under acceleration and more frequent filter checks.
Q15: How difficult is the installation?
A15: It is straightforward with basic hand tools and typically takes about 45-90 minutes. No cutting or permanent modification is required.
