Works greatt

The K & N filter for my 2003 Honda Goldwing is well made but, it is floppy and you have to make sure it's well centered before putting the housing back on. I would like to see a firmer casing which would be a lot easier installing. But that's me.

Hubby bought it for his Honda Valkyrie. He disassembled his bike and installed the filter himself. The filter is in and works well so far.

I've got K&N air filter in my motorcycle. Good quality and good for long term use, since it is washable and reusable.

I have always liked using K&N filters. I only gave 4 stars because this one I got was over lubricated in the package and ended up fouling all my plugs so I had to take it back out, clean it, and lubricate it properly. There weren’t directions that came with the filter to let it sit and cure or dry for 20 minutes like the recharge kit explains. First filter I have ordered with this issue though and I would still recommend K&N to any and everybody!

Definitely undertake the replacement on your GL1800 if you haven’t. Taking off the top shelter is just a few bolts and connectors. Make sure you disconnect your battery as you’ll be fumbling with ECM and Cruise Control modules (they’re literally bolted to the top cover of the air box.) Brought my Goldwing back to life after a mouse made a happy home in ALL of my intake airways.

Reviews on this filter in Amazon seem hot and cold, and while I am usually generous with my stars and kind in reviews, this time I am going to be more critical than usual because K&N has not done well engineering or manufacturing this particular product.The filter element part itself is fine. Typical K&N design with pleated cotton/ wire mesh, sealed all around in a pliable rubber compound. Seems like more surface area than stock. However, the flange that actually holds the filter element and provides the seal between the airbox and its cover is not designed or executed nearly as well as Honda's supplier did on the stock Honda filter.The Honda filter uses a strong plastic flange to hold the paper element. It fits the sealing grooves of the airbox (and cover) precisely and holds the filter element rigid above the throttle bodies. The K&N uses a molded rubber flange which does not match the air box sealing grooves very well and when finally secured in place, it lets the filter element move up and down as if it is mounted in a diaphragm - which essentially it is. It seems as if the rubber compound used by K&N shrinks or expands a little when it comes out of the mold, making the fit "approximate" to put it kindly.I got the thing in and it will probably work fine. However I had a hard time and could not be sure the raised bead of the rubber flange (which is supposed to eliminate the need for the existing O ring) was in the lower sealing groove when I got the lid down and secured. It kept wanting to pop out of the groove as soon as I released finger pressure.I badly needed a new air filter (see below) and wanted to ride the next day, so out came some trusty Permatex Hi-Tac cement and I made sure this expensive, ill-fitting thing stayed properly in place while I screwed the lid down.K&N air filters that I've bought and used before have been great, but this one needs to be re-designed so it is mounted in a rigid flange similar to the OEM Honda filter. After spending around $50 to buy this then having to goop it up to make sure it stays in place makes me think that the OEM filter is superior, and probably the one I should have used - to say nothing of it being half the cost of the K&N.The GL1800 1st Gen has been out how many years now? And K&N, a brand that many turn to, because it is a "high performance" product, supposedly "better" than OEM, has had this product on the market this long? Unbelievable. I'm surprised this isn't a hot topic on the forums... Whoops... It is. Kind of like which oil is "best"... Nippondenso or NGK... Floorboards or not... Whether Yellow is the best color on a Wing... Or Blue... Or not... Decisions, decisions...To show how well the OEM Honda filter holds up, see the picture of what I discovered when I burrowed into the bike and opened the airbox of my new (to me) '08 'Wing. The bike sat at the dealer for sale as a used machine over last winter, and it seems a mouse family had made a cozy home in the airbox while the bike sat there. Some of the pleats on the Honda filter had been eaten away and the filter seemed totally plugged with their pee and excrement, but none of their stinky "stuff" or their babies had gotten past the filter and into the airbox. Thankfully. Absolutely no idea when the air filter had been last serviced (dealer said it was all serviced and ready to go--NOT!). Even so, the bike ran like a new one with all this stuff covering the filter, another testament to the reliability and forgiving nature of the 'Wing, and the compensation built into modern electronic fuel injection systems. Now if they had just made the darned filter easier to get to. And perhaps mouseproofed it as well!My conclusion: Stay with the Honda filter. Change it as recommended, probably less than every year for most riders. You need to clean the tupperware and clean and inspect under the shelter anyway. Besides riding, what's better than to lovingly work on your beautiful machine on a Saturday afternoon with some cold ones nearby? Unless you can sneak out of work to do it instead, leaving Saturday free for riding!

I mean, it’s a K&N so…For me it’s a real problem changing the air filter because I ride a Goldwing. For that reason this filter is a must. It adds almost 60,000 miles between recharging and the recharge kit (up to 10+ uses) costs less than a stock air filter. Add to that, the higher air flow, increased horse power and time saved in labor, all of which make this purchase a no brainer.
