Review: Toyota Tundra 4.6L 2011. Wasn't Expecting Much,…was I Surprised Updated Dec 2017 - *****Update dec 2017: No issues at all, still great mileage! Saving me lots of money...even more whenl gas goes to $8.00 a gallon! Excellent! Perfect fit and seal around the lip of the filter. I am comparing performance to a brand new stock Toyota dealer supplied filter. Wasn't expecting much. Was I surprised & this filter delivered impressive results. 1. No low /high speed noise or whine on my 4.6L v8. In fact, just a quiet, mellow rumble that really sounds great. Nothing radical, just sounds like it should for a big, powerful engine running well. 2. Situation where I notice the biggest difference is in town, low speed, starting from stops, and especially when the engine is still cold. It's like the engine was driving with it's nose stopped up but now, the sound is clear and flowing. By that I mean when engine is cold or starting from a stop, any hesitation is gone. It breaths right through it. Engine does not sound stopped up and interestingly, the transmission shifts more smoothly, too. Not sure how the air filter plays into that but smarter tranny shifting is a definite result and improvement e.g. it tends to release /shift into a lower gear sooner, which increases mileage in and of itself. MY dash MPG gauge reflects the difference I am hearing in sound and shifting leads to higher MPG. 3. I have an instantaneous and average MPG gauge and I can see in all my driving situations (no trailer or big load) getting 2-3 MPG more. That's a 10-15% increase. I am impressed. But with my MPG gauge, I have a highly trained foot with no lead. 4. Highway cruising under 57mph is 24mpg flat highways; over 60 & MPG drops noticeably. Combined mileage 18-21 MPG on this big Tundra. Maintenance: Says it's good for 50k miles. You don't have to clean & re-oil until then. I bot their kit for 10$ that comes with a cleaner spray, oil spray, and clear instructions. I would sugg using the SPRAY oil to recharge the filter and not the oil in a spout bottle where you have to drip it onto all the filter folds. A Spray is MUCH quicker and more uniform. So it comes either way as a spray or in a drip bottle & price is about the same so not a factor. Overall I am really pleased. At a price of 40$ incl shipping I cannot think of a negative. After ordering my filter I noticed the price went up 30% for no apparent reason. The 4.6 Tundra just rolls easier,... and it's like a rag was taken out of it's nose with the K&N 33-2387 filter and the engine can finally breathe!
Review: Do it! - Awesome filter. Improved airflow and better mph.

## Questions & Answers

**Q: Can someone please describe what come in the package?  My packaging seemed old and the only thing it had in there was the filter,**
A: My package was like new. Filter was in plastic wrap with a solution that kept it fresh when opened. Installed easily and has worked really well. Notice a slight performance increase but with the cold weather coming in, I haven't really been able to determine any better mileage. It is good to know that this is a premium product that will last a long, long time.

**Q: Do I need to do anything to the filter before I install it?**
A: The K&N High Performance Air Filter 33-2387 is ready to use straight out of the box. The filter can last up to 50,000 miles between servicing, depending on driving conditions. With the K&N Air Filter Cleaning Kit you can easily clean and re-oil your air filter bringing it back to brand-new condition and ready for another 50,000 miles of use.

**Q: Does this need to be oiled right out of the box?  Instructions on how to oil?**
A: No
 It is preoiled. Just pull out of box and install where the stock air cleaner was.

**Q: I have a 2020 Tundra with 5.7 will this filter fit**
A: Should be, but, make sure to check the Filter number to match your truck,

### ⭐⭐⭐⭐⭐ Do it!
*by S***. on March 25, 2026*

Awesome filter. Improved airflow and better mph.

### ⭐⭐⭐⭐⭐ Excellent Filter. Exposes design flaw with 5.7 L Toyota Sequoia and Tundra which can be resolved
*by M***W on March 19, 2013*

Pros: Excellent filter with excellent airflow to your engine. Will last longer than the vehicle with routine cleaning and spray oil, so saves money in the long haul. Cons: Not a "Con" for this filter.. a "Con" for Toyota: Installing this filter exposes a flaw with the Toyota 5.7 Liter engine, where a very high pitch sound is generated by a metal mesh located behind the throttle body. The OEM filter masks this noise (likely becuase of its density and restricting airflow). To correct this, remove the two bolts holding the throttle body to the intake manafold (after first removing the air filter housing) and then use a pair of wire snips to clip out the wire mesh from the gasket behind the throttle body. Replace and high pitch noise goes away. (I installed a new stereo arround the same time as this filter and thought the noise was the radio... very high pitch and sounded like it was from the speakers inside the cabin... enough to drive someone crazy looking for it).
