Bel-Ray Foam Air Filter Oil

Super tacky oil, i use this for the raptor and the trx90, but i prefer pj1 for my trx450r super tacky too you can’t go wrong with bel ray or pj1

Bel Ray filter oil is very good and hasn't let me down yet. I appreciate the competitive price and the prompt delivery received. I will recommend RMATV to other riders. Thank you.

Easy to apply I recommend that everybody use this if you were running a foam air filter blouse maximum cover for performance

I use a fresh coat before every ride. I'm sure it has good longevity but I just feel better running clean air every ride.

Ive used different brands bel ray is the best for me pour it in a tub dip your filter squeeze out and your done little messy on the hands if you use a tub a bottle last a long time

Best oil on the market easy to use have used for years without failure

this is the ticket buy again & again when needed. A go-to filter oil

This was the only mx filter oil I purchased but the spout has changed recently and it makes a mess so I'm going to switch to another brand.

Great stuff,, period,,I have used it for years ,,and never ever had any dirt go through it or around it ,,just all and great stuff

Have used this stuff for a while now and I am very pleased with it. It does a great job.

Very sticky. No dirt gets by. A little messy to put on but it works.

Easy to use. Way better value than spray cans. Doesn't make filters cold and hard when applied like spray cans...which increases life.

I have been riding dirt bikes for 30yrs. this the only filter oil I use and never had engine failure due dirty air. This oil is cost effective, and has superior performance, blue color ensures even oiling. this stuff is so viscous/ sticky that it can be tricky to get on evenly and get it completely out of the filter when dirty. Use nitrile gloves and a extra large zip lock type bag to apply. Pre oil the bag, then spread in bag, then add filter to ensure even coat. Use kerosene or solvent first, then hot water dawn dish soap to clean. a little grease around the air box where the filter mates up and your are golden I use it in my dirt bikes, chain saws, weed whackers, even RC nitro engines. If it has a foam filter, it gets BEL-RAY F.F.O. It just works. Simply the best foam filter oil EVER!

I have been using this for a few years now and think its the best filter oil to use in the dust or mud.

I like it! It does what it's supposed to do! And it turns your air filter blue which is cool

Excellent qualiy. Doesn't let anything through! No dirt no water!

I have been using this filter oil for over 20 years and haven't lost a motor to dirt yet.

RM is great! Orders are always made easy and delivery is speed. As for the foam oil it does the job and I will continue to use this product.

I've used this for years and loved it. But, the last bottle I bought seems to be a much thinner formula than before. After servicing my air filter like always, I noticed a LOT of residual filter oil running down from my airbox. I didn't oil any heavier than usual.

I keep telling myself to try the no toil products, but why mess with something that works? Clean your air filter with mineral spirits, then dawn dish soap, apply this filter oil and your intake will look amazing.

Awesome stuff! I've always used this stuff along with other Bel-Ray products. Never let me down

I've used Bel Ray for years and still happy with its ability to catch dust and dirt. if it didn't work well would have change years ago.

Great product from Bel-Ray. Total engine protection.

-m-2017 KTM 450 SX-F--

Use gloves when applying, sticks like their chain lube and keeps the dirt out

-m-1990 KAWASAKI KX500--

Using BelRay air filter oil for MANY years. Never had an engine failure due to dirt passing thru filter. Very sticky blue oil permeates filter well & is also very waterproof too (great oil for wet enduro).Use rubber gloves as this stuff will stick to you for a long time. I pour the oil into a dish-cleaner squeeze bottle for precise & controlled application as the bottle has a large opening & gushes out a bit too fast.Dark blue color shows well for coverage. Only brand i CHOOSE to use for my air filter.

-m-2017 KTM 300 XC-W (E-Start)--

Great oil. Started buying this because it's available in larger quantities than what I was using. Won't be going back to the other stuff.

-m-2002 HONDA CR250R--

It is an awesome product. If oiled properly in super dusty conditions, the filter will clog and bike quit running but still won't let dirt pass through filter. I have had it start running bad on top end and still finish the race and air intake still perfectly clean

-m-2008 KTM 200 XC--

im no chemist but its stays on the filter and the dust stays out of the carb

-m-2014 KAWASAKI KX65--

Have been using bel-ray filter oil for a long time. It is nice and tacky, so it doesn't let any dirt into my motor. That is important!

-m-2014 KTM 500 EXC--

Great stuff been using it for ever I always inspect the inside of the filters after removed and I never see dirty spots. Must be doing its job.

super tacky, won't run off.
Best I have ever used in my 30 years off road riding.

This oil is the tackiest filter oil I've used yet. Does a great job at keeping the GA red clay dust out of my motor. Be sure to use mineral spirits or kerosene to clean it out because soap and water won't cut it.

Good stuff. Thicker than some others making it easier to apply. Good price.

Best protection available and easy to clean.

I have been using this for a few years. Works very well keeping the dirt in the filter. Not as easy to clean as the bio stuff, but effective.

Bel Ray makes great products. This air filter oil does what it's supposed to do. I like the easy pour spout too. Will buy again.

I'm in the air about this product, it's very thick and hard to apply thin enough to not make a mess while on the bike.

I stick with one product for all my filters. Bel-Ray is good stuff.

Only oil I'll use on my filters

I've been using this stuff for years and it work great! Wouldn't buy anything else.

Bel-Ray products are always quality and priced well.

Works well

After years of trying different oils (UNI, UNI BIO, Twin Air BIO), this is the best I have found. I prefer the petro based because it speeds up the cleaning process and I actually use less water than with BIO oils and I end up with cleaner filters. Very little if any dirt gets through.

Excellent product

very sticky, and I like the easy use spray can. cleaning can be a bit tough, make sure you have the right solvents outside of plain soap/water otherwise you will have some work ahead of you.

Yeah buddy!

I have used this filter oil for years and never had any issues. Bel-Ray makes excellent products.

I have used this filter oil since it came out. It keeps the dirt and dust out and gives me many more hours on my top end.

Good stuff, been using it for years
