Actually, I just had my car in for its 30,000 mile service today, and she runs SO much better now. I never really read the service summary, so I didn't notice that the spark plugs were going to be changed, and man, what a difference! My car was jerking during shifting, too...I couldn't figure out what I was doing wrong -- had I suddenly lost my ability to drive a stick after fifteen years of experience?? That was it; she is very smooth & responsive now. They also found a broken motor mount, which is bizarre, but it was fixed under warranty...

man my plugs where bad compared to urs

iTrader: (21)

how bad? lol btw before w/stock plugs= 30 mph city, 40 highway, with iridiums =40 city 40-43 highway.

40 city?? cmon man..............ur city must be different than my city, lol

when we say city.........well, it really depends where u are, right? lol

i usually get 30-32 in city (mixed) and 40-42 in highway.....

but this highway aint 60mph....80mph straight at about 4-4.5K rpm


and gear.....like i said before about stock plugs....i can't see why that stock denso platinum should costs $10.24 each + shipping from hondaautomotiveparts.com

that means, if u go to local dealer they (stock denso PKJ20CR-M11) costs $13.66

at that price, why wouldn't we just go with denso iridium IK-20?

i live in the atl. you live in ny. your car sees nothin but traffic. and yeah i cruise 80 and get 40+. i drive a stick though so it helps. my ride sees traffic sometimes. when im in the city i cruise at 50 or 60. so as long as i keep the rpms around 3k im set.

Can anyone tell me how to get the damn spark plugs out?? My brother has a 99 Prelude SH and i want to check his plugs but they are in there deep. After loosening them, how do you get them out?

zen_master

iTrader: (6)

u gotta buy a special spark plug socket...there's a rubber inside of em which hold the spark plug.....therefore, you can pull it out..

Black02Civ

ok thanks. I'm looking to buy the Denso I-K20 for the lude, but i want to know if they are universal for all apps, cuz there is no specific car choice on Dezod.

you need a socket extender and a special socket with rubber in it to pull the plug out.

zen_master

iTrader: (6)

^^u might want to check www.sparkplugs.com

btw.....just a quick question to all of u..

is there anything such as "break-in" period for spark plugs? i believe.........or maybe just in my imagination, my engine is a bit noisy with IK-20.....especially when VTEC kicks in about 3300-4000RPM....

or maybe it's just on my mind?

tinman

You can also loosen the plug with a normal plug socket and use a coil pack to pull the plug out.

Mine need changing, so I'll try them out for myself.

there is a saying from honda that your not supposed to have a tune up for 100k. but thats bs. we have seperate ignition packs for each of our cylinders. the spark is hot as bawls. so i changed mine as soon as i bought my car in february. the car had 56k on it and my plugs looked old. so i changed to iridiums and i believe they will last me for 40 to 50k. i will check every 20 k to make sure. so yeah. btw go to walmart. they will have a socket for your plugs. have fun

I need to change my plugs. I've had the ngk irridiums on the car for like ... ever. I've been to busy with my new job these past few months. I'm getting the Denso ik20 today. It's cheap and quick to change out. Off to the auto parts store I go.

zen_master

iTrader: (6)

please help me with this

especially if ur changing ur plugs with ik-20 also...

on the 3rd pick the one on the right seems to have some ignition timing issues...either there is not enough fuel going into that cylinder or your getting predetination when the compressed air fuel mixture detonates because of compression stress not spark plug going off...it looks to me that you need to clean your fuel injectors cuz it is most likely running lean...and if there is too much air and not enough fuel vapors than it will burn hotter than usual causing sparkplugs to burn up and piston heads to get carbon build up...also the bosch platinum 4s absolutly do not do anything better or different than a standard single rod platinum sparkplug...this is comming from many experience auto tech instructors/professors...but of course iridium spark plugs work better than stock but and old spark plug will do when it comes to breaking windows...lol! hehehe *evil grin on face*

^wait da minute...

ur talking as if you can check em out cylinder by cylinder...how do you do that??

i probably have to take em out again.....review the condition of each plugs.....and probably swap em around?

or maybe the whole thing is just my imagination....there's really nothing wrong with the sound during idle....it idles normally at about 550.....

it's just when i rev it during the period when the time vtec kicks in....it sounds a bit noisier....

oh actually, i just put a bottle of fuel system cleaner during the time i change my plugs.....so, i doubt it's the fuel injector clogging..

ragingSPAM

iTrader: (8)

well that could have been build up before u put the fuel cleaner in cuz that kinda stuff takes time and to do a check do a compression check on each cylinder...if u can take it to a shop where u have a friend or a mechanics which u go to all the time and ask cuz that kinda stuff and tear your engine up over time and fuel efficiency goes down...

edit: get it checked than next time u pull your plugs out get a sharpie and write down the cylinder number on the sparkplug as you pull them out and show a technitian see if one is still blackening out more than the others

also get a spark plug gap checker and check manufacture measurements
