I just bought NGK IRIDIUM plugs and like to know if you guys noticed any difference in gas milage,performance,start up...

ou sig

I had 80k on the stockers when I put in the new ones...my mileage hasnt really changed at all with any of my mods, no noticable speed performance but there was a difference with smoother startup, idle and overall engine performance

whatwasthat

how much did you get them for and where? I'm looking for a set..

btw, ou sig, did you change them yourselves?

Ebay actually - for like $6/plug or so, and yes I put them in myself - very easy.

Didnt notice a thing with my Denso Iridiums

i have platinum plus4. my idle is very quiet and when starting up the engine, it starts really quick. when i just leave it on idle it sounds like the car's not even running. im so happy i got rid of those stock plugs.

aaronnn

oyeah, but i didnt notice anything with the gas mileage or the car's performance. no gains in acceleration or whatever, all it did was make the engine alot smoother during idle or when just cruising..

Just replaced my plugs a couple of week ago with the Denso Iridiums IK20 plugs.

Got them off ebay for ~$45. No noticeable change in mileage or performance.

i got a smoother idle but thats because i replace the originals at 115k. the densos arent in good shape any more, rough idle again and way past their life expectancy. im going to NGK iridiums

hey guys, you noticed the smoother idle and quiter engine right away but the acura dealership also recommends resetting the computer in the car after doing plugs so it recognizes the upgrade,, do this by unplugging the negative battery cable for at l;east 15 minutes then put it back, the on board computer will go through a system check and recognize it, i put new plugs in and noticed the smoother idle and start up right away too but once i heard you had to reset the computr for the rest i did notice some gains in fuel mileage and wayyyy smoother acceleration. the computer just needs to pick up the new plugs

@cUr@-TL

so you bought them uh?


i'll talk to my buddy at Acura as promised and i'll call you back about that engine/misfire issue.

okay guys, i'm about to go on ebay to buy the spark plugs... which ones am i looking for?

enter just NGK iridiums? do they all work in all cars or is it car specific?

whatwasthat

is there a DIY guide to this?

whatwasthat

this is from an ebay description from a seller:

NGK IRIDIUM IX SPARK PLUGS Honda Accord V6 Acura MDX TL
One SET of 6 NGK Iridium IX spark plugs. If you want 6 spark plugs, please click "Buy Now" only once. These are stock # 2477, part # ZFR5FIX-11

is this the right plugs for my 2000?

theres another buyer down the list, they're selling for 40$ buy it now. but description says its only for acura TL. ... are both the same??

99TLHeather

These are stock # 2477, part # ZFR5FIX-11

is this the right plugs for my 2000?

These are the correct ones to get for a TLP

etxxz

gotto sparkplugs.com and look for the TL plugs and it shows all the part #s.
use search for a thread i started about april-july 2004 and it has the DIY...very easy
MAKE SURE:
Engine's cold
Do 1 spark at a time
you have the right plugs and have the same size

^^my friend got wrong sized plugs (bigger), did the front 3 at the same time while the engine was hot and it cost him $2700 to get a new head @ the misubitchi dealer (3000gt) THE MOST EXPENSIVE PLUGS IN HISTORY!

FFWDGRAPHX

I have about 115,000 kms - should I change them now? If so what is the best type of spark plugs for my 99 TL

Thanks in advance.

just reread this thread. the best ones are the NGK iridium plugs. ebay has em for $38 shipped. i just ordered some yesterday... ifyou're wondering which part ## to get, read my posts above.. those are the right ones.. i'm pretty sure TL-P and TL-S are the same...along w/ 1999-2003 plugs..( correct me if im wrong people..)

obespalov

Can anyone confirm this? Does this only apply to acura TL?

No noticable difference.

i just installed this today. like everybody said, the upper left corner one is a bitch to get out. but luckily i had a tool called, "swivle spark head head remover" this tool made everything so much easier. btw, theres a noticable difference in idle/acceleration. drive much smoother now..

whatwasthat

FYI: the tool i used was so easy to use and i recommend it to everyone who will change their plugs.. it fits perfectlky into that tough spot. it's only $5 at autozone. i bought it at the last minute to change the upper left corner one. only if i bought it earlier, i would of been done in about 15-20 minutes flat.
