It's a pinned post that people with queries about spark-plug types and gaps can consult without having to start fresh threads each time.
I know but it doesnt mean anything to me. How do i know which ones to use?
The first five letters/numbers ("B205E", etc.) refer to the engine type of your 9-5. B205 is 2.0 litre; B235 is 2.3 litre; B308 is 3.0 litre v6. M** is model year. "R" suffix is Aero HOT.

If you use the VIN decoder (http://www.saabtechtalk.com/forum/index.php/topic,21.0.html) it will tell you which engine you have :)

Thats what i mean. I dont have any of the ones listed. I have the B235R 260HP :P
All B235Rs use the same plugs.
THERE we go! Thank you for that information :D
Tuned Aeros (2.3HOT, B235R) - NGK BCPR7ES-11. Change the set when you change the oil+filter.
i use BKR7E-11 in my 3.0V6 petrol, thats NGK`s recommended one. whats the difference between 6E and 7E anybody know?
steve
Price and heat dissipation ability.
Just looked at NGK website and they say for 2002 9-5 aero hot the spark plug is BCPR6EIX-11 ??
Is this a better plug for me to fit rather than the BCPR7ES-11
mine is Hirsched 280BHP
Don't know which bit of their site you're looking at but their pdf catalogue says PFR6H-10 for the 9-5 Aero which is what Saab say too so I'd use them *unless* Hirsch say to use a different plug.
Looking at their partfinder section .. states the model number you just posted but then as an upgrade the BCPR6EIX-11 number, just had a look and its basically an Iridium plug .. think they use them on the 3.0l V6`s but they are £60
Ive just ordered the 7es-11`s from ebay for £8 as someone on this thread said they where for the Aero HOTs .. I hope they are right

Aaah, I'd just their recommended and not bother with an "upgrade" as they usually turn out to not be. The BCPR7ES-11 are not the suggested plug for your car but will be fine, given how cheap they are just replace them every year.
Thanks Quino ... Ive got to sort gearbox soon on her she`s getting more and more jumpy now so want to do it before it fails on me, Ive emailed Saabtech in Stevenage asking for a quote as they seem to have a good rep

As quino says, the expensive (c£10 each) PFR6H-10 are the spec for the Aero.

Hirsch say Do Not use the platinum 6's as per standard aero. The plug for this tune are the cheaply 7es gapped at 1.0.
Had plenty of email exchanges with them in the past!!

Sure - I was just clarifying what the correct plug for the stock Aero is, in response to the quoted post which implied otherwise.

Ah nuts .. just ordered the 6H- 10`s which where £30.00 are you sure the above is correct Paulo
Dealer still uses the PFR6H-10 on my current Hirsched Aero.
Whichever you have, I wouldn't worry too much. The PFR6H are platinum coated for longer life. The other plugs are fine, you may just need to change them more frequently.
You can normally pick up the platinum ones for around £25 a set on eBay- here's some of the current listings:

The electrode tip is actually solid platinum, not just coated. It's also a different shape and size to the BCPR7:

;D on a side note I am a very happy man today as I just came off the phone with Saabtech in Stevenage, they can uprate my autobox it will be £2000 but when I asked how much NM of torque I could put through the uprated box he said "put it like this .. you wont be able to build an engine with enough HP to get to its limit" :o
Sounds like they up-rate all the internals and fit a bigger oil cooler
Regular re conned box fitted was £750 which I thought was reasonable
I asked hirsch 3 times to check, each time it was use 7 es and not plats.
P
I put the es 7`s in man what a difference
Living is Oz with a tuned LPT I decided to change to 7es plugs, made quite a difference - cooler plugs reducing onset of knock etc...
hi all,recently i had my my02 9-5 aero tuned and after reading this forum i am still unsure which is the correct plug for a tuned aero.before the tune i was usins the pfr,s and left them in with the tune and car runs great.after reading this topic i then tried the 7es 11,s as this thread seems to suggest and car again runs great,i am just looking for some clarity as to is there a specific plug for a tuned aero over a stock one.car seems to run the same whatever plugs i use.
My Hirsch Aero with 300hp runs on the standard platinum plug.
But I've heard two things, and I can't confirm the truth either way....
1. The only reason that the platinum plugs were used was to keep the service interval of the Aero the same as the other models.
2. That if you change the plugs more often, the normal plugs used in the other cars are OK. I think Maptun use these.
thanks sgould,there seems to be no hard and fast rule on this one.i think i will stick with the non platinums for now as i do change them often and car seems to run well with these.
This may well be a complete load of rubbish but..... I once read when running a tuned car and driving hard the injectors are slower to react than the ecu wants them to act causing fuel to be sprayed onto the plugs when no fuel is required for example when changing gear at high revs, now apparently as the platinum tip plugs only have a small electrode the fuel can stick/pool on the tip and stop them firing or limit it, but because standard plugs have a bigger electrode that heats up any fuel sprayed on them is evaporated so they contine to fire correctly.
uum,food for thought that saabman,thats a new one to me but not beyond the realms of possibility.will be interesting to see if anyone else has any thoughts on that.
Sounds like a flawed theory... apart from providing the spark, one of the other things plugs do is conduct heat away. The electrode on the platinum plugs is much smaller than regular ones, so if anything it would be hotter and thus more likely to burn fuel. But then agian they are all categorised in heat ranges to take care of this
But... how does this reconcile with the fact that a turbo car in hard driving mode will be mapped to run rich i.e. more fuel than can be burnt anyway...
If anything, it strikes me the risk might be that the hotter electrode temperature might cause pre-ignition, so if you're runnig na tuned car, best off to run a colder plug, regardless of whether it is platinum or regular.
I run BCPR7ES-11 re-gaped to .9mm on all my tuned Saabs as recommended by Lord Noobtune.
The theory is by closing the gap by .2mm gives a fatter spark, I change them whenever I do the oil & filters, normally around 5k miles on the 95Aero 19t with 342bhp and 500nm same on my 93og trackcar with 466bhp, I get fewer knock lights on T5. On T7 cars its alledgedly better for the DI.
