Most Lexus IS350 models use a 24-inch driver-side blade and a 17-inch passenger-side blade. Sizes can vary by year and market, so verify for your specific car.
Typical sizes for the IS350
The two most common blade lengths you’ll encounter on an IS350 are:
- Driver-side blade: 24 inches
- Passenger-side blade: 17 inches
Note: Some markets or model years may use 18 inches on the passenger side. Always confirm for your exact vehicle year and market.
How to confirm your exact size
To be precise, check a few reliable sources before buying blades:
- Owner’s manual section on wiper blades for the recommended lengths.
- A sticker near the driver’s door jamb or inside the glove box listing OEM blade sizes or part numbers.
- Online parts lookup or dealer/retailer site: enter your year, trim, and market to retrieve the exact blade lengths for your VIN.
Once you know the exact sizes, you can purchase OEM-equivalent or aftermarket blades in those lengths with confidence.
Choosing the right blade type
Size is only part of the equation. Blade technology can affect performance in rain, snow, and freezing temps. Here are common choices:
- Framed blades (traditional): generally economical and easy to replace.
- Beam blades (frameless): offer better contact with modern windshields and often improved performance in winter.
- Hybrid blades: a mix of framed and beam features for balanced performance and durability.
When selecting, consider climate, driving conditions, and ease of replacement in your region.
Maintenance tips
Replace blades at least once a year or sooner if you notice streaks, chattering, or missing sections. Clean the blades and windshield regularly to extend blade life.
Bottom line
For most Lexus IS350 models, the standard combination is 24 inches on the driver’s side and 17 inches on the passenger’s side. Always verify for your exact year and market via the manual or a reputable parts lookup.
Summary
The IS350 typically uses a 24/17 blade pairing, though some model years or markets may vary to 18 inches on the passenger side. Confirm the exact sizes for your car to ensure proper fit and optimal visibility.
