How to change spark plug in Polaris 2017 Sportsman 450 HO.
I was able to change spark plug in about 10 minutes.
Update 2/22/24: Going in from the right side (removing right panel) is a little faster.

The hardest part was finding the plug. Thanks for the video. Much appreciated

[@snusmumriken6091]

Phillip Crook really?

[@phillipcrook8336]

@@snusmumriken6091 yea. Actually finding another plug was hard as well because Im not a city dweller. No NGK or CHAMPION plug matched so I actually had to go back to a polaris dealership and purchase 4 extra auto⚡lite plugs. Taking it out and replacing it was a sinch

[@puchski1]

Thanks for restoring my sanity; I was beginning to think I was the only one that thought this was a difficult routine!

[@ljonesto]

puchski1 How’d it go?

[@bcjdwbiernfjherwfbowfib]

I ended up removing all 3 intake pieces and it made it very easy. Thanks for the video.

Thanks for the information and taking time to post the vido to help others like me. The kids just inhance your vido, making it real. Kids and pets, always make better 🤗

[@dalerichards5303]

Good vid'.. Thank you. However....I used a 3" straight adapter AFTER struggling with the swivel. That proved to be, maybe, the best option. Thanks again. 👍

[@ljonesto]

Thanks for the info, I will try that next time.

[@chrisbull2436]

I had to change the plug on my 2018 so I'm guessing everything is the same. However, I have to day, I didn't have to dismantle anything. Once I knew where it was ( thanks to this video ), I could easily reach in behind the front ( brake side ) tire and pull the cap off. I even tried the tool that came with the bike and after a little manoevering to find the "sweet spot", I was able to use the tool as well. However, the little 90 degree tool that inserts into the top of the spark plug wrench to turn it is very slight and short so it was difficult to get enough leverage to turn it. My point is, based on what I have just said, a plug can easily be changed on the trail with what you have. In your garage with better tools etc I can certainly see the benefit of removing panels and the like but in my case in the time it would have taken me to do that I had the plug changed. Great video though!

[@ljonesto]

Great to know Chris, thank you

[@christopherchastain-nv6re]

helpful video thanks for the info changed plug started right up

[@rippinadventures4458]

thanks man. the hardest part was taking off the blue cap but i go it

[@johnh9520]

You dont need to go through all that, take off the OTHER panel instead. It basically give you much better access to the plug with no further need to remove anything else. Use a deep 5/8 thin wall socket. You dont even need a extension or swivel, its stil a tight area but much, much better...fyi removing that panel also gives you much better access to the stupidly installed battery terminals. Your welcome.

[@ljonesto]

Thanks I will give that a try

[@ljonesto]

I assume you mean the panel on the other side?

[@johnh9520]

Yes the right side panel, sooooo much better, you can also access the horrible position of the battery much easier. Good luck

[@Lucky_Moe]

Thanks for the iinfo. I one modification I would do is change the plug from the right side... you won’t have to take the air snorkel off.

[@ljonesto]

Matt Fast thank you. Will give it a whirl next time.

[@dalerichards5303]

Just did it from the right side and it is easier than the left. Thanks again for the vid.

[@ljonesto]

WOW right side a lot easier

[@fredwalters3210]

Polaris engineers must change everything every year. Probably just cant get it right. My 2016 450 Sportsman spark plug is right on top just below the gas fill cap. I tried a new NGK BKR6E today. LOL, screw base is much larger than the NGK in machine. Back to Adv. Auto tomo!!

[@ljonesto]

Engineers like to test our patience LOL

[@donfrommpls778]

Nice video, thanks!!

[@Psychodermia]

Dang ol' kids! I'm tryin' to learn something here! 😂😂😂😂

[@theastro-philosophersappre2786]

Thanks, gotta love those kids!

[@kemhardemon2367]

Thanks for your help?

[@stewp.3298]

Thank you !

[@dirtzilla500]

next time remove seat, remove air box lid, plug is right there, 2 minute job.

[@rickgillard2296]

Any tips for pulling the wire off? Mine feels like it's welded on..with the limited access my old hands cannot get it to break free from the plug..

[@ljonesto]

Sorry Rick I don’t. Might need to get creative to get some more pull on it. 🤞🏼 Best of luck. Let me know.

[@rickgillard2296]

@Lou finally got it..used long needle nose pliers right under the square part at top of plug wire..then used the exhaust as leverage point to pry upwards..

[@ljonesto]

@@rickgillard2296 what size and year ATV you have?

[@rickgillard2296]

​@@ljonesto same as you..2017 sportsman 450 HO

[@stevegiroux8943]

I need to replace the spark plug wire on my Polaris magnum 325 4x4 year 2000 can you show me how to replace it without taking the total front plastic pieces off please thank 🙏🙏🙏

[@ljonesto]

Sorry Steve, I am not familiar with that machine. Wish I could be of more help. You can post your question in the Polaris ATV Forum Or even search for it there. Forum is filled with very helpful people. www.polarisatvforums.com/ Or you can just do it and post it to you-tube and there will not be a shortage of comments on how to do it a much easier way 🤣

[@johnw2167]

A better plug would be a NKG (BKR5EIX) it"s an Iridium plug

[@ljonesto]

John W Thanks John. Spark plugs are a bit of a mystery to me. I figure a spark is a spark. But like anything else there is alway better quality out there. Curious to know what makes the NKG plug better? I do use them in all my other ATVs because I always here good things. What type of machine do you have?

[@johnw2167]

Same as yours Polaris 2017 450

[@disarmyou84]

Hey I have a 2020 Polaris sportsman 570. How does the seat come off? I wonder if it’s similar to your 2017.

[@ljonesto]

Can’t be too sure but I assume so. You will know right away if it’s gonna pop off or not. Let me know.

[@salvadoralvarez2875]

Fuel ingector for Polaris

[@ljonesto]

?

[@ljonesto]

Yes it’s fuel injected

[@thomashenderson603]

how does the seat come off?

[@ljonesto]

Thomas Henderson just pull up on the back of the seat. It may require some force. Then once it is lose you will slide it back and out. 👍🏽 What machine do you have?

[@TheRealJohnHamp]

What's a transmission intake?

[@ljonesto]

Lol. I had no idea what that part was called. Any idea?

[@davestrauss8919]

Remove the air filter cover and is the only thing you need to remove

[@ljonesto]

Hey Dave, do you mean remove the air filter box?

[@davestrauss8919]

No just the cover

[@wilsonaviles8439]

Why did you feel you had to change the sparkplug?

[@ljonesto]

Wilson Aviles I like to change the fluids, plugs & filters annually on my machines. And in this case, for the Polaris, I also needed to make sure I could do it while on the trails if I needed to.

[@madmade6877]

Because spark plugs fail LOL especially if you run it rich or mess with your choke hell there's a thousand Reasons it's a good no.4 DIY

[@BeerLeagueGoalieGodfather]

@@madmade6877 these machines are EFI, no choke, mix control. runs cleaner and much longer plug life.

[@darrenhicks94]

What size spark plug socket did you use?

[@ljonesto]

Darren Hicks I used 5/8 inch spark plug socket.

[@snusmumriken6091]

ljonesto fuckin hate your metricsystem

[@austinjames3488]

BKR6E- 6962 the manufacturer plugs are junk, autolite is what they put in fords off the line and i hate them

[@ljonesto]

Austin James thank you. What machine do you have?
