Default A cross post to another thread, regarding 2.5l engine and spark plugs

Seems NGK only offers the super platinum plugs for the 2.5l. These plugs are very expensive. Read my thread in the legacy forum about an alternative and tell me what you think..

I've got regular ole NGK plugs in my car. Cost me $7 for all four.
I don't know why you were led to believe otherwise...

You can definitely buy non-platinum NGK plugs for the 2.5l. I am running plain old copper NGK V-Power plugs, always have. I think the part number is BKR6E-11 for the plugs I use.

tcs007:NGK's web site and all of the distributors do not mention an application for the standard plugs.

RebelINS: How do your plugs look? The platinum use a slightly higher heat range, do yours come out okay?

I have the exact same plugs that RebelINS has.
I went out to my car and checked, just to make sure of the part number.

And I wasn't calling you a liar or anything. I just know that they exist, because they are in my car right now.( And probably due for a cleaning/checkup for anything funky.)

No offense taken. Thats what is currently installed in my legacy 2.2l

I personally do not own an ej25 based machine. Just trying to help someone out. Are you sure they are the correct heat range though? Do they come out clean?

The plugs are a perfect fit, and work great. They came out clean, even after I blew a couple O2 sensors, and had my car running rich.

I order all of my spark plugs from here. This in turn takes me to:
http://www.ngksparkplugs.com

Looking under "1999 SUBARU Impreza RS 2.5 H4 EJ25D MPI DOHC", this is the result.

V-Power - BKR6E-11 # - Stock#2756# - Plug Gap .044

Platinum - BKR6EVX-11 - Stock#3540 - Plug Gap .044

The V-Power plugs can be found at the site I order from 1 degree colder (BKR7E-11) or one degree hotter (BKR5E-11) in V-Power. Platinum NGK's can be had one degree colder (BKR7EVX-11) or one degree colder (BKR5EVX-11). I order ALL of my spark plugs from Monarch Products because their shipping is fast and reliable. I hope this helps.

Default Oh.....

I'll add this for 'added punch'.

The V-Power plugs are $1.99 a piece and the platinums are $6.40 a piece. So for $80.00+, someone has been had.

"tcs007:NGK's web site and all of the distributors do not mention an application for the standard plugs." Ciper, look again at the V-Power plug application that I mentioned. You'll notice a pound sign (#) next to it. That means it is the Original Equipment plug for that application.

What the hell? I just went to their site again and they DO NOT list that plug...

qoute
1997 SUBARU Legacy GT 2.5 H4 EJ25D MPI DOHC

Spark Plug Part No. Stock No. Plug Gap Photo
Platinum PFR5B-11 * 2300 .044
* Laser Platinum Plug

end qoute

That is all the plugs listed for the application.

So its a mistake in the page or subaru ONLY uses platinum in the DOHC engines or something. You are right, when I look up 99 2.5 rs it shows both of those

The P/N for the NGK coppers is in the manual. ciper, do you have a Napa store near you or your friend? Had them in stock the last time I changed them in my RS. I have a set of stock Champions with light miles on them, for sale cheap!

It may not be a matter of engine, but application, Ciper. There are lots of external factors which also influence the heat range of a spark plug, such as air/fuel mixture, engine speed/load, etc.. Just because Legacies, and RS's use the same base engine, doesn't necessarily mean that they require a plug in the same heat range.

Default PFR5B-11...

... is what my manual says for my 97 Legacy Outback Auto with EJ25D engine.

My dealer put some new ones in recently because they broke one of my TorqueMaster plugs. Cost for NGK platinum was around $50 Canadian IIRC, or about $30 odd dollars US for 4. That's about $8 US each from a dealer.

Heck, the TorqueMaster plugs didn't cost that much... and I thought they were expensive at $14.50 US each.

Julian: that may very well be, but I DONT have a 2.5l! I was helping someone else

gavin: Im the person who was saying that the heat range was incorrect, your explanation should be pointed at someone else.
