ok so my car is at 92k and i know i have to change the spark plugs but i never really understood what exactly does the spark plugs do for the car..if i change them, what difference would i notice on the car?

 

Newer plugs will give a cleaner spark which means a more complete combustion. This yields better fuel efficiency, better power, cleaner (greener) exhaust, etc.

 

The car will run much more efficiently as stated and most importantly engine will not hesitate due to loss of power because of old worn plugs.

 

I know the manual will give a scheduled time to replace them but what are people on this site doing?

 

idk how often people here are doing it..but reason i asked was because everytime i start my car it kinda jumps a little to hard..and the engine shakes more then normal also when is running..hopefully that helps but we will see and im going to honda dealer and get them from there which is $18 from the accord. i mean it has the same exact engine so pretty much everything you will need for the tsx you can get it at a honda dealership...but not everything though.

 

Hi All,

I checked the NGK Site and the Plugs recommended are Laser Iridium ones ( Model 6994).

These are selling for 10$/ a piece at amazon. The dealer quoted 90/- for four..

I am going to check whether the local auto parts stores sell these..

Yeah, the TSX comes with Iridium plugs from the factory. That's how they can recommend a 110k service interval on them. The local Autozone/Discount Auto Parts should carry them as well. Don't think they'll beat the Amazon price though.

 

I just bought two different kinds of NGK spark plugs used in Acuras at Pep Boys and Auto Zone. The ones for the 2004 TSX and the ones for a 2003 TL 3.2. All of them were $9.99 each, plus tax--at both parts stores. I installed the TL ones yesterday and the TSX ones today. They are great. It seems like it makes a difference, but it could be the placebo effect, too, I suppose. Mine (TSX) weren't too black (only 61k miles on them), but the ones on the TL were quite singed (84k miles on those).

 

So what i'm understanding is that the Iridium plugs only avantage is that they last longer. I like to change my plugs regularly thus if I use copper or platinium plugs there should be no difference in performance ??

 

Not necessarily.

Also this: http://ngk.com/glossary.asp?manID=1&kw=Iridium
Not to mention that there are no other listings from NGK for our car, so you really don't know if a copper or platinum plug will fit precisely (thread depth, gap, etc) or if it'll work perfectly with the TSX ignition system.

 

If you are getting vibrations it sounds like more of an engine mount issue.

Your plugs do need to be replaced but I'd look for a more mechanical reason for the shaking.

 

Makes sense.
Wheres the best place to get NGKs in Canada ?
Thanks.

 

For our car? Not Canadian Tire or PartSource, that's for sure. They don't carry the particular plug we need. I'm sourcing mine through a local auto parts dealer, about $17/plug.

 

just changed the plugs on my wife's 05 TSX with the NGK iridiums and at 106k miles they looked in better condition than my platinum plugs did on my jeep that only had maybe 40k miles on the plugs.

 

Did the car drive better too?

 

New spark plugs will only make a difference if your old plugs are bad. Simply replacing plugs will not increase horsepower or make a world of difference. The OEM plugs should go strong and stay relatively clean until 100k miles or so. There are tons of variables that can affect your plugs so it never hurts to check them before it says.

 

I'm replacing my plugs tomorrow. How important is it to apply the anti seizing lubrication? And is that all i need other than the new plugs?

 

If you are using new NGK plugs, do NOT use anti-seize. They have technical papers (I have one in my email inbox from them) that state that their plugs have a "special shell plating" (aka: Trivalent coating) on the threads that act as a one-time-use anti-seize. They specifically advise against using anti-seize on the plugs upon initial installation for prevention of over-torquing.

However, IF you take the plugs out at some point in the future, then you should use anti-seize at that time.

Google "NGKSP-0907-1" for their technical bulletin I got this information from. Again, I received this straight from NGK themselves via email. It's also available here: http://www.ngkplugpro.ca/content/con...SparkPlugs.pdf

 

Ok thanks. Then my last question is which plugs are better? Should i get the NGK or the denso?

 

I believe the NGK's are OEM and are what everyone I talk to says are the best for Honda/Acura cars. I'm getting some this weekend myself.

 

Partsource said they can get them for $20.00 each. I call NGK Canada and they wanted $30.00 each !!
TB on the question should or shouldn't gap new plugs...

Sorry this link should work...

I don't know if you can get down to the USA at all, but Advance Auto Parts has them for $9.99 USD. I'm getting a co-worker to pick up a set for me next weekend when he's down there for his semi-monthly trip to get groceries and stuff at much more reasonable prices in upstate NY as opposed to Ontario.

 

Ok i just picked up new plugs and i'm confused. I got NGK IZFR6K11 6994 from kragen's and i'm confused if these need to be gap or not. Its hand written on the box to be 0.044 but i saw another thread that said it needs to be 0.047. And worse the guy at the store told me these are not pre gapped0and should be checked. Can i just pop these in or not? Thanks.

 

They should be 0.044" and do NOT attempt to gap them - the electrodes could break and then you're SOL.

 

I measured the gap on one of the plugs and it was around 0.040 which seemed to be slightly out of the tolerance. But the guy at the auto parts store said that should be fine. So can i just plug these things in?

 

Yea, you can just put them in and go.
