The Honda 2007 Fit service manual has the NGK: IZFR6K 13 and Denso: SKJ20DR-M13 as the recommended spark plugs.

 

just look it up for an sr20det

 

Half the population is below average intelligents.

 

I'd like to change the plugs in my Fit, because leaving the stock ones in there for 100,000 miles seems like a recipe for trouble.

I'd hate to have the dealer tell me they had to Helicoil any of my cylinders because the original plugs were welded in place...

I know, it is a forum, not a spelling test...

@jkskrn - the best thing about Fitfreaks.net is that it is NOT honda-tech. While people have the right to post their opinions, the rest of us have the right to ignore them. Keep on keeping on and thanks for the DIY. Helpful!

 

I did this yesterday. This thread was super helpful. Thank you! It wasn't that hard. I stopped worrying after I got the plug out that was hardest to reach.

 

correct me if wrong... other than F/I, the best candidates for colder ik22 plugs are the ones with performance intakes and exhaust?

 

You can use it on a N/A application and get more ignition advance from lower combustion chamber temperature.... If you don't drive aggressively with the revs fairly high during the colder months of winter, they may extract to much heat from the combustion chamber and could foul.... It would seem that something like this wouldn't happen but I have had cold plugs in vehicles that would start missing, or one or more plugs would completely foul in freezing weather.... If I have trouble with the ND IK 22s as the temperatures drop this winter, I will post it here... That may be too late for you guys that live in colder climates if I have to post.

 

^^ very reason I'm still keeping my IK22s in their box.

Do update on how it goes

 

idk what plugs i got but i will post up soon they were just a bit shorter then the oem ones but i believe the are an ngk somethin idk

 

I'm seriously thinking of going to IK24 as suggested by J's Racing with their reflash. Though, I may wait till around March when temps begin to climb up some for the very reason TC stated. It definitely goes below freezing here, but the winters are pretty tame from what I experienced last winter. Though many are predicting a much colder winter here. Who knows.

 

Any feedback on the IK22's? I'm debating between IK20 and IK22's. I don't care what any wannabe car guy has to say. I have had Denso Iridiums on 3 cars now and all 3 picked up hp on the dyno. One picked up 23 whp, but that was an extreme application. My Fit needs plugs and I don't mind spending the money for the best. They pay themselves back in fuel over 50,000 miles.

 

If it sparks it blows.

 

waste of money on a stock engine

 

LOL...these comments about not worth the money, waste of time, etc are hilarious. Do you people not realize that spark plugs are a maintenance item? These plugs are the same price as the originals and you have to change plugs regardless of which kind you use.

These ridiculous statements are the equivalent of saying that it's not worth the time or money to change your oil.

 

im pretty sure your stock plugs are good for 60,000-100,000 miles.
if you want to change your oil every month, then all the best to you.

 

Honda calls for plug replacement at around 75,000 miles, but valve adjustment at around 60,000 miles. I am nearing 60,000 miles and I figure it is easier to change the plugs while the intake and valve cover are off. That will get me to the 120,000 mile mark when I will do both again.

I am not the kind of person who sees cars as disposable. I have put well over 200,000 miles on several cars and plan on doing it with this one. A little preventative maintenance goes a long way. $30 for a set of plugs is cheap maintenance.

I change the oil every 5,000 miles and use good oil and filters. Maybe you see all of this as silly, but I take pride in taking care of my stuff. Most people these days are wasteful and don't appreciate the things they have. That is why I only buy new cars or used ones from people that I know and are like minded.

 

The ECU will advance the ignition timing higher with colder spark plugs and improve power output and fuel mileage... I have had problems by using a spark plug that was too cold for winter use but only on motorcycles and pre OBD2 cars... There shouldn't be a problem using cold plugs in a Fit engine as long as the coolant line that heats the throttle body isn't bypassed, but as canuck901 said you will have slower engine warm up and a problem with fuel dilution of the oil when it is very cold... Even with the stock spark plugs there is going to be oil dilution occurring in a very cold environment.. You can sniff your dipstick and tell that there is gasoline present in the oil..

 

I know, old post. Anybody with IK22 have any problems in cold weather? Thanks for any info

 

Whenever I'm able to get under the hood for an extended length of time I am going to put IK24 plugs in place of the IK22s... I had 2 heat ranges colder plugs in my GMC Safari cargo van with Hypertech tuning and a Mallory HyFire ignition booster...... I wish there was something in the way of an ignition booster that was less than $400+ like the HKS one.
