The Toyota Celica GT, a sporty coupe popular in the mid-1990s, requires regular maintenance to keep it running smoothly. One crucial component is the air intake hose, and specifically, part number 17881-74540 often comes up in discussions regarding the 1995 model. This guide will delve into this specific part number, exploring its function, common issues, and where to find replacements.
What is the Air Intake Hose and Why is it Important?
The air intake hose is a vital part of your engine's respiratory system. It's responsible for transporting the air from the air filter box to the throttle body. This clean air is essential for combustion, and any restriction or damage to the hose can negatively impact your engine's performance. A damaged or deteriorated hose can lead to:
- Reduced engine power: Cracks or holes in the hose can cause air leaks, leading to a lean air-fuel mixture and reduced power output.
- Rough idling: Air leaks can disrupt the smooth flow of air into the engine, causing rough idling and potential stalling.
- Decreased fuel economy: Inefficient air intake leads to inefficient fuel combustion, resulting in lower gas mileage.
- Check Engine Light: In some cases, a severely damaged hose can trigger the check engine light, indicating a problem with the engine's air intake system.
The 1995 Toyota Celica GT's air intake hose, identified by part number 17881-74540, is crucial for maintaining optimal engine performance. Ignoring a damaged hose can lead to more significant and costly repairs down the line.
Where to Find Replacement Part 17881-74540?
Finding a replacement for part number 17881-74540 is relatively straightforward. You can source this part from several places:
- Toyota Dealerships: This is the most reliable source for genuine Toyota parts, ensuring a perfect fit and quality. However, it might be the most expensive option.

How to Identify if You Need a New Air Intake Hose?
Regularly inspecting your air intake system is crucial. Signs you might need a new hose include:
- Visible cracks or holes: Carefully examine the hose for any damage.
- Loose connections: Ensure the hose is securely attached at both ends.
- Kinks or bends: Severe bending can restrict airflow and damage the hose.
- Unusual engine sounds: A whistling or sucking sound might indicate a leak.
What are common problems with the 1995 Toyota Celica GT's air intake system?
Beyond the air intake hose itself, other components within the 1995 Toyota Celica GT's air intake system can also cause problems. These include:
- Air filter: A clogged air filter restricts airflow, similar to a damaged hose. Regular filter replacements are essential.
- Mass Airflow Sensor (MAF): The MAF sensor measures the air flowing into the engine. A dirty or faulty sensor can affect the air-fuel mixture.
- Throttle Body: A dirty or malfunctioning throttle body can also negatively affect engine performance.
Regular maintenance and timely replacements of worn components are key to ensuring the longevity and performance of your 1995 Toyota Celica GT.
Is it difficult to replace the air intake hose myself?
Replacing the air intake hose is generally considered a relatively easy DIY repair. However, it does require some basic mechanical skills. Consult your vehicle's repair manual or find online tutorials for a step-by-step guide. If you're unsure, it's always best to consult a qualified mechanic.
This comprehensive guide should assist you in understanding the importance of the air intake hose (part number 17881-74540) for your 1995 Toyota Celica GT, where to find replacement parts, and how to identify problems.
