Where do you guys usually get your airfilter for those of you that have an adapter for the MAF. I need a 4.5" air filter and cant seem to find any at the local parts stores i have in my town.

Do you guys order yours usually online or am i missing something?

 

You will have to order online, no place is going to stock a filter that big unless its for a Ford F900 super duper duty or whatever they are and in that case it's not gonna fit. Amsiol makes a great filter, might have to get a diff. maf adapter. Unless your running a 42R 4.5 is a bit large. Just my 0.02

 

try AMSoil there good filters and they have dif sizes

 

No one will have them instock but any major auto parts store like autozone and so on can get them for you no problem. I got my K&N and AEM filters from autozone, I placed my order at the store and paid up front and I recieved them within 2-3 days.

Here are some 4.5'' filter options with some info when you need to order:

K&N Filters:

Part # RU-3480 4.5'' / 6'' length / 5.875'' base outside diameter
Part # RU-4260 4.5'' / 5'' length / 5.875'' base outside diameter

AEM dryflow filters:

Part # 21-206DK 4.5'' / 5.125'' length / 6.5'' base outside diameter

Autozone can get you most any filter.....hope this helps.

 

Haha no im not running a 42R(I Wish i was)...but i have an adapter plate connected right to my MAF and i measured it across and it was about 4.5 inches. Its the adapter plate that Buschur racing sells that connects right to the stock Intake/MAF Setup and comes with a vibrant filter i think.

 

Did you try lancershop,hopupracing,stikiller etc?

 

maybe ask buschur?? if thats where you got it from they would be the best bet id say

 

i ran a perrin filter on the maf adapter for a few months until i purchased the rest of their intake. they are pretty cheap filters, around $50
