i bought a set of the NGK, worked fine for 3 months, after that i had the same problem, purchased another set from a different supplier in January, so far so good. i hear the v-power, as long as gapped properly, they work fine as well.

I have Irriidium plugs in my RB25 for almost a year now and never had any problems. Good info on the fake ones, will definitley look out for that when I am buying again!

[CD4Accord]

I'm glad that I am importing plugs from the states for all my vehicles, at least that way I dont have to worry about the fakes...

A real shame that the consumer has to be abused like this in T+T

i think the "denso" irridium are good though...correct me if i'm wrong

[RyoTech PerFormance]

We at Ryotech Peformance will like to inform our customers that ALL NGK / NTK products sold buy us are directly imported from NGK Japan and are 100% Genuine.

I had a customer who bought a set of iridiums or platinums (can't recall) from a popular NGK retailer and the grounding strap actually broke off near the apex. They didn't even last him 24hrs...... please check for genuine markings when buying to prevent problems.

Denso makes two kinds of iridium plug.. A long life version and an ultra-fine tip "performance" version..

If going denso, go for the long life... The shorter lifespan isnt worth it for the .05hp or whatever the finer tip will produce..

That said, if you can get genuine NGK iridium IX, then its a superb plug..

[5forward]

how do i go about telling the difference between the denso "long life" version and the "performance" version?

Fake NGK Spark Plugs

Fantastic info.
Thanxs VegA!!!

[CD4Accord]

The Denso plugs have different product codes.. I dont know them offhand but it can easily be found online...

The tip diameter is also significantly different between the two models and so is the packaging, naming etc..

Sorry I cant search right now but im on the school cumputers.. Just check out denso website

[dreadman]

i recently bought a ga15 head an block an with it i got denso plugs out of japan(not iridiums)........working good. actually i find it workin better dan d iridiums

[rez]

i need to buy plugs for my rb20det but i am going to tune for 350hp what is a good spark plug to use.

[~Vēġó~]

no problem guys.....glad to share the info!

[CD4Accord]

Well, my NGK iridium IX needed to come out of the accord... I don't know if one or all are fouled, but when I had the spark plug oil seal leaking, some oil got in there and really messed up my plugs..

Changed the seals and cleaned the plugs but they never seem to have recovered and just as a temporary diagnosis measure I threw in some ngk v-power and the car idles fine again..
I guess incidents like this remind me that sometimes you can never really get the full life out of iridium yes..

Next rounds I may try the Denso Platinum TT... For about $2.50 US each in the states why not

[5forward]

If im buying online ill buy the denso iridium...but which is better: IK20 OR IK16 ?

another question: My car (corolla dx wagon) has a sticker on the head cover stating to use spark plugs with two electrodes...how important is this?

[CD4Accord]

The difference between the IK20 and IK16 is the heat range... 16 equates to NGK heat range 5, 20 equates to 6...

For my particular engine the 20/6 is what is required because of the compression ratio etc...

Concerning the twin tip, I can't see it being that important but if you want piece of mind just buy some Denso Platinum TT for $2.50 US and that way you get your twin tip...

alrite...but doesnt a spark plug with 2 electrodes suppose to look like this http://www.google.tt/imgres?imgurl=http ... 40&bih=809 ? ...the plug in the sticker looks like that
