About this product

Part #: 63-1043

The K&N AirCharger 63-1043 air intake system replaces the restrictive factory air filter and air intake housing in some Toyota Tundra models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Tundra's engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 63-1043 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. The placement allows air to be directed through a custom molded intake tube into the engine's throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

What made you choose this particular product?
I had K&N in all my previous cars and never any issues. All bought from the UK because in my country the same product is up to 50% more expensive.
Is this your first time buying from this brand? Did you consider other brands?
No. I have considered other brands, but price-wise I did not bother.
Was it easy to install? Any installation tips that will help others?
Very easy to install. When in doubt, check on youtube.
Once you've had a chance to use the product, did it meet your expectations?
Yes, it is a small improvement. Better airflow does not give you big HP gains, but the engine responds more smoothly. And it already was smooth before.
Any additional comments?
when cleaning an air-filter always use the correct products. Also when re-lubing let the filter soak in the lubrication for at least 24h-48 hours. So make sure you have a cheap back up filter as a temporary replacement.
