K&N Series 57 FIPK Cold Air Intake without Heat Shield (97-02 5.4L F-150)Find parts that fit my vehicle

Well constructed upgrade for 99 F150 XLT

I am very happy with the finished product now that I have this item installed on my 1999 Ford F-150 XLT. The increased airflow has definitely improved my truck's overall performance, and I love the sound it creates that is missing with the stock F-150 Intake system. But I was the first to turn over my breather cap on my 1967 Mustang when I was much younger in the seventies, and I have missed that V8 sound since they changed the systems. The quality of the K&N CAI systems is legendary, and this has been on my mod list for several years. The quality is superior, and you will not be disappointed. This does come with instructions. However, the images are small, and my wife and I are not mechanical, so it presented a challenge for us to install. It took us the better part of a day to put this all together. We could not find a YouTube video showing this model from K&N, but in the end, we followed the instructions and got the job done with no missing parts or problems. We could probably now do the same job with the same parts on the same year and model truck in an hour. Our youngest son is a senior diesel mechanic for a heavy equipment company in Nashville, TN, and our oldest son has owned his own automotive repair shop since retiring from the Army, so we also sent them pictures and asked for their helpful guidance. In hindsight, there was a $125 professional installation option, and it may have been a decent investment option. But overall, we enjoyed the challenge and now can look at the installation with some pride. Would I recommend this CAI system? Absolutely, and I am glad we purchased it. Once we tackle the new BBK Throttle Body install and put an Optional Tune on the truck, it will be the beast it was designed to be, like my 1970 Ford F-250 Highboy.

Good k and n air filter kit

It is the best k&n air filters to buy it sounds amazing on the truck

definitely worth it

it was easy to install and looks way cleaner than having the stock intake.

Replacement air filter

K&N filters are #1 in quality you get what you pay for. Old filter was trashed had to be replaced. K&N was a no Brainer. With an increase in air flow over stock filter, engine runs smoother with a slight power boost. Fuel mpg also had a positive result.

Good product

Noticed improved acceleration and some fuel savings. Instructions could have been a little more explicit on which hardware to use. But overall satisfying with it

Great!

I have had this for 3 years with no issue! Great product

Intake replacement

Just installed on my 98 F-150. The only issue was the temperature sensor hole was to big for the sensor. I installed a rubber grommet in the hole so sensor would be snug with no air leaks. Total install time was about 1.5 hours due to the sensor.

Air intake

Good quality and takes like a hour to install and looks and sounds great

All around great

Everything in the box was amazing quality parts and I can definitely tell a difference in the power of this old truck. It also made it a lot louder, even with a stock exhaust just the new intake makes it sound like a muscle car.

Great especially paired with 75mm bbk

Bought together with bbk 75mm throttle body only thing is combining both you will need a tune
