THUNDERMINGO 17093030 TBI Assembly
This assembly is listed for 1993–1995 Chevrolet and GMC 5.7L V8 vehicles, including C1500, C2500, K1500, K2500, Suburban, Yukon, Blazer, and Tahoe applications, with some model-year limits. The listing gives replacement numbers 17093030, 17091058, 17092081, 17091041, and 17091042.
Best for: Owners whose vehicle and existing part number match the stated applications. It was selected for its clearly described model coverage and multiple reference numbers. Caution: Blazer and Tahoe fitment is not listed for every year, so check the specific model-year details rather than assuming all 1993–1995 versions fit.
17093030 Assembly With Fuel Injector
This listing identifies fitment for a Chevrolet 5.7L V8 from 1993 through 1995 and gives part numbers 17093030 and 5235206. Its description also claims a robust construction intended to handle heat and pressure.
Best for: Buyers who want a listing with a short, specific part-number reference and a stated 5.7L application. It was selected as a straightforward option to compare against assemblies with longer fitment lists. Caution: The supplied fitment details are less extensive than those on some alternatives; confirm your make, model, and original number before purchase.
Auto Parts Prodigy Complete Assembly
The listing describes a complete assembly for 1993–1995 Chevy and GMC 5.7L 350 V8 applications with OE number 17093030. Included items are described as fuel injectors, a throttle position sensor (TPS), an idle air control (IAC) motor, a fuel pressure regulator, and a base gasket.
Best for: Buyers seeking an assembly that lists several related components together, rather than a throttle body alone. That component list is why it stands out for comparison. Caution: The listing makes claims about drivability and emissions results, but those outcomes are not guaranteed for every vehicle. Verify exactly what is included and confirm fitment before ordering.

Best for: Buyers whose original assembly number appears among the listing’s many references. The broad number list makes this a useful option to cross-check. Caution: A long replacement-number list does not establish that every number fits every vehicle; compare the exact number and application for your truck or SUV.

Buying Guide: Choosing A 5.7 TBI Throttle Body
How do you confirm fitment?
Start with the vehicle’s year, make, model, engine, and original throttle-body part number. Compare those details with the listing’s stated applications. The products here focus on 1993–1995 5.7L V8 vehicles, but listed model-year coverage varies by vehicle. Do not rely on engine size alone.
Should you choose a complete assembly?
Choose a complete assembly if you want the listing to include related parts such as injectors, TPS, IAC, a regulator, or a gasket. If you only need a particular replacement part, check whether it is included rather than assuming every assembly has the same contents. The supplied product details vary in how thoroughly they describe components.
Which replacement number matters?
Match the number on your original unit to the replacement numbers provided by the seller. Some listings cite only two numbers, while others provide a longer cross-reference list. A listed equivalent is a useful starting point, not a substitute for confirming the vehicle application.
What else should you check before ordering?
Review the product description for model-year exceptions, included hardware, and whether the item is described as new, remanufactured, or otherwise. If the listing does not answer a key fitment or contents question, confirm it with the seller before buying.
Frequently Asked Questions
What does TBI mean?
TBI means throttle body injection. These products are listed as throttle-body assemblies for specified 5.7L V8 applications.
Do all 1993–1995 5.7L Chevy and GMC vehicles use the same assembly?
Not necessarily. Fitment depends on the specific vehicle and part number. Check the listing’s model-year details and compare the original number.
Are fuel injectors included with every option?
No. The listings describe different contents. Check the individual product details to see whether injectors and other components are included.
What part number should I check first?
Check the number printed or stamped on the existing throttle body, then compare it with the replacement numbers stated in the listing.
Can I choose by engine size alone?
No. Use engine size along with year, make, model, and the original part number to narrow down the correct replacement.
