4PCS 54mm Air Filter

Good quality product! Fit great on my 2004 Triumph Bonneville. Thanks.

I got this hoping it would fit my Predator 420 with the upgraded air filter and it did... but its TIGHT. 9.9/10 for the money its very much worth it.

Not bad for the money. Put them on my ‘81 CB-750C, until my K&N’s come in. They work well so far.

Well made part

Received the filters on time. Shipping was pretty prompt and fit as expected. The problem with the filters though is that they very easily disconnect from their own rubber mounting housing. It isn't bad enough that I'm going to go through the hassle of trying to send them back, I'm going to use them because the filter is really good quality (comparable to K&N but half the price) and looks great but......... I'm going to have to apply a little two-part epoxy between the filter and the rubber housing and I would suggest that anyone that buys these, do the same because they will blow off with the slightest back pressure from the carbs.

This is a good replacement air filter for the Grom. Same size as K&N and Chimera intakes.

First off I like the look of these pod style filters. Their design of the filter itself is top notch. It is so much more durable than the stock air box crappy filter. At 3k miles I was doing maintenance on my moped and took the air filter box cover off to clean the filter and re-oil it, and it was dissolved and clumped up inside the air filter box! Sounds terrible I know. These filters help bring in more air. It did make my moped louder, but not to much in my opinion. It also makes your engine run leaner, so your going to have to adjust the carburettor idle screw so it revs a little higher. Also, I DO NOT recommend running this straight off your carburettor! the design of the pod filter covers up the intake jet ports on the carburettor which could cause your carburettor to stall out. What I did was I kept the old air intake plenum on the carburettor, then run a piece of angled pvc pipe off the plenum, then attach the pod filter on the end of the pvc pipe.

Nice

Filters look nice and are dimensionally accurate. Who knows about long-term durability. I gave the filters 1 star due to my first order of filters only containing 2 filters, after returning the filters and reordering assuming the first order was a mistake, I again only received two filters.
