I went to pick up a K & N cone air filter for the how to posted here on the site for making a cold air intake for the Celica ST. I knew I needed a 2.5" inlet, but all of theirs were 3" or greater. They said they could order one, but needed the part number. Any of you that did the CAI, can you give me the filter's part number?

Thanks!

Sorry not sure, I used a 3". You can get 3" to 2.5" silicone-based couplings pretty cheap.

One of the Web sites I was looking at the filters at replied back and said they had the RX-4860, which has a 2.5" inlet and is 6.5" in length/height. Will that work?

Anyone know if that RX-4860 K&N cone filter above will work?

just get the one with the clamp, mine was 3 but i just screwed the clamp till it fit fine.

knfilters.com go there and pick out the style your looking for ie: stright or tapered and then find one with correct Mounting Flange Inside Diameter. Even if it's close to 2 1/2" you'll be fine it is rubber so it does stretch a bit and you can clamp it tight if it's a bit loose, I would't recomend going as big as 3" though. good luck!

i got the RX-4010, ordered it off of www.n2performance.com. Its a smaller filter, so it worked PERFECTLY, fitting in under the battery and radiator coolant reservior. Best of luck. PM me if anything else!
