i just got a trd filter off ebay for 20$ with adapter. i dont know if that is good or not. ill tell you how it performs when i install it. however, Beowulf recommended that the traditional one be used. after mine wears out, ill probably take his advice. After all, he saved Herot!!
 
After reading K&N air filter website, I am sticking with mine. Its talks about how the dirt in a paper filter builds up on the surface vs. a K&N where it builds up through the whole width of the filter.

Also here is a link about the MAF issue from K&N website. I think the key is to not over oil your filter when you clean it.

I've had two K&N's on our 60, here are my thoughts:

each time I installed the K&N, I replaced a filthy stock filter. of course there was a performance gain, but I suspect a clean paper element would have helped too!
When I switched from K&N to paper, I got a big gain. Again, the K&N was very dirty, the new filter clean. Go figure.

I'm running K&N now because paper elements are hard to get here- most 60's here run the 3rd world style filter housing, I've got the US style housing... so the K&N saves me hassle of looking for paper elements.

I don't really think that the K&N is better, and I miss being able to blow out the paper filter... I haven't had to clean and re-oil the K&N yet, that'll be an adventure as I'm sure nobody here carries the supplies.

For a DD, the K&N is probably great. You can ignore it for a long time.
For a wheeler, I like the paper as you can see when it is clogged up.
For an expedition style rig, I like the idea of having a spare paper filter on hand, but it doesn't really matter if there is a K&N or a paper in the housing.

Just my 2 colones (not many pennies, I'm afraid)
 
I've had my K&N for about a year now and I haven't had any problems what so ever. Although I've been thinking about getting the paper one back in there just for peice of mind I guess.
 
after having them on several vehicles, I still think they are a waste of $.

there has never been any empirical evidence to support the fact that they are better (that I have seen).

i see dirt when i see a dirty paper filter. i see nothing when i see a K&N.......that means?

Same thing with also, but if you have already they I guess why not use it, but if U'r thinking about buying one then I just say to not even bother unless you have the cashh to waste otherwise I would go ahead and just go with the paper one just to be safe and after all there pretty cheap also.
 
Okay...for you die-hard fans of the Paper Filter...a Toyota OEM washable PAPER filter! This came in a kit that included the OEM snorkel and OEM snorkel air box with the cyclone and intake port pointed towards the fender to accept the snorkel fitting.

The Toyota part number...which should work should any of you want to order one up:

The filters in question side-by-side for comparison...NAPA paper filter (my OEM was at home), OEM reusable paper filter, TRD performance filter, and the much-maligned K&N filter. You will note that there is a lot of dirt visible from my dirty TRD filter which has only about 10k kms on it...so it does work well.

It's another interesting addition to the debate, anyway. :beer:
 
Want something else to chew on for a debate ???

It's fairly common knowledge in performance racing circles that by increasing the air column pre-maniforld will result in great engine torque.

The K&N filter is smaller.

Does the K&N because of it's smaller size increase the torque capabilities of the motor ? And would the torque be measurable ?

:D

I've had K&N filters on 8 rigs in the past 14 years ranging from 4cyl to 8 cyl - does it really make enough performance difference to warrant it's use? it never did for me. Is it a good filter? yes I think it is. Do I buy them anymore? no I don't. I like messing around with my motors and I would alway find myself checking the K&N anyways-a habit hard to break. It boils down to personal/rig preference just like tires and shocks and lights and....... :beer:
 
been running them for years and will continue. started running them because in illinois, cruiser parts weren't that easy to find and the air filters were expensive (about $18 vs. $24 to buy a k & n). grant it, that was fifteen years ago, but since then i believe i've saved a signifant amount of money by running k & n's and i haven't had a motor with any major failure and less than 300,000 miles...either i've sold the vehicle with a couple hundred thousand miles, or it's gone over 300k. here's a pic after my last utah run...looks pretty clean on the inside.

Great comparo, Stone. Great pics. Thanks.
 
Will that filter fit my '72 "F" engine canister???? If so, I want one!!!

Could you measure the opening for me???

I had a noticable increase in performance (acceleration, less smoke) when I installed my TRD filter AND snorkel. My fuel consumption stayed the same. In fact, noticed this on both BJ74s that had the snorkel and performance air filters fitted on. Maybe it's the fact that there's a turbo and the cold air intake coupled with the less restrictive air filter made that much more air/oxygen avialable? Don't get me wrong...it didn't turn my BJ74 into a sports car or anything...:D But improved it none the less. Is it really worth the money just for the increased performance? No, I don't think so. But I horse-traded an extra GPS that I had for the snorkel...so it didn't cost me as much as retail.

I've had positive results and good luck...

I have ran K and N filters on several vehicles for 10's of thousands of miles. I have a 96 Jeep with the 4.0, ran the K and N from about 35,000 to 82,000 miles with no problems. I have run them on two different Dodge trucks. A 1991 Dodge Dakota with a 5.2 ltr for about 88,000 miles, no problems what so ever. I never noticed a great deal if any performance change. I did notice slight gas mileage improvements. Also out of the 10 years I owned the dakota and the 5 years I have owned the jeep, I have bought two filters. I'm sure I got my moneys worth there. I have never had to buy cleaner or filter oil since original purchase as I am still using the original cleaner and oil. Two filters, two vehicles, 15 years and 135,000 miles of great service and no telling how many filters I did not have to buy. Plus they have a million mile warranty. They do void a lot of factory dealer warranties. Fuel economy on the jeep went from about 15.5 mpg to 16.9 mpg after switching to the K and N. Just my personal experience....
