install K&N filter 2003 Thunderbird

Has anyone installed the K&N Filter kit (69-3520TP) and had any issues with the vent hoses not fitting into the K&N intake tube (27321)? Is the tube milled wrong as not to accept the vent hose? It there any modifications besides honing it out to the correct diameter to have the hose fit?

I found it tight too, but I inserted the hose into some very hot water to soften it up then used some dishwashing liquid to allow it to slip on easier. Great sound for sure! go easy on the oil when you clean it though lol

I had the exact same issue. There was no way the stock hose was going to fit onto the K&N nipple even with heat and some lubrication. I ended up MacGyvering with some 1” heater hose and a clamp. 7AB2DDA2-8076-4C43-B7E4-CA48A9CE749A.jpeg

I installed a kit in my 2004 TBird, i don't know the part number, but you use the hoses that come with the kit, not the ones on your car. I removed at least one hose as i recall. It took me about 1.5 hrs start to finish, with a little cussing mixed in. I did not have any issues with fitment.

No hoses included. Instructions were to use the stock ones. One fit, one didn't. Also cussing included, but I love the result!

YES!!!! I ended up triple wrapping black duct tape. Of course, I will have to check periodically to see if they are cracking. Good so far.

I went to a junk yard, found a 99 and up Lincoln LS V8. Took off the factory vent hose with the 90' elbow that goes into the valve cover. I then made a slit along the hose that is heat shrunk to the elbow, removed the elbow and Vala, Had a stock elbow that snaps into valve cover and the supplied K&N rubber hose slips right over the elbow and the nipple on the air tube
 
Just saying the hole on the K&N snorkel was 0.850". Diameter on the hose is 0.875" and original ID on stock air filter is 0.900". Hope i is flexible enough when heated to shrink that much. K&N is no help although they sent another snorkel to me at no charge. After 15 years someone should have corrected production somewhere.
