1999 B4 spark plugs

[flange]

Hey guys,

I'm running single turbo setup with sti ecu etc. and need to get new plugs.

http://www.dsrturbo.com/ngk-spark-plug_bcpr7es.html

Will these do the trick?

I'm gonna order some once I found out if they're ok.

Don't mind if I have to change them often.

Wouldn't the copper ones just not last as long?

Think the marketing of the others are the mark up.

Searching copper vs irridium says they overheat more than copper.

Just wanting to know if they fit?

[Joker]

I am in not way experienced BUT I reckon they would melt within 200km on boost

but you can give it a go and let us know the results?

I'm waiting for some more technically minded users to comment on cheep plugs vs factory recommended

[scoobygt]

I have heard they make turbo subs miss, platinums or iridiums is what most people use

[B4 2000]

Yes you could use them but you'll probably gonna have to change them every 10,000ks max?

another option is BKR7ES, they cost the same! << i was going to get these but cant be bothered changing too often.

im going to use coppers and just change them when i do a oil change . rather then waiting for a expensive plug to s*** its self.

they just wont last as long but copper is a better conductor then both iridium and platinum

^^ As above

Iridiums only make sense if you're paying a mechanic to be changing the plugs, copper will do the job 100% perfectly at a fraction of the cost

Example - a lot of mitsi V6's get recommended iridiums in rear, copper in front - sicne the front bank is a 30 sec job to change vs 2 hrs for the rear

+1 accepted in most workshops on V6 engines.

Only thing wrong with using coppers is their longevity. Perform well and are easier to find in the 7 heat range.

then why am I paying upwards of $20+ each when the $5 are just as good?

[scoobygt]

marketing I think

Cause they last four times longer. So its a moot point.

they probably gave you better performance because the old ones weren't up to task any longer..... a spark plug is a spark plug

[scoobygt]

yeah haha first this was a g box thread now spark plugs haha interesting

[Jesus]

Still on my first set of plugs at 220,000kms and 10 years.

Wasnt keen to change them since the cheapest i could find anywhere was $27+ at trade each. AC Delco just released a new platinum plug for a quarter that so finally going to put some new ones in. Bet ya it makes SFA difference.

They also do a cheap platinum plug for the 4 cylinders and turbos if anyone wants hookups.

[DRFVDR]

You would be surprised how much a new set of plugs make a difference

done the missus's Audi v6 one awhile ago it had done near on 180000 ks with the original plugs, the old ones were will buggered, the new ones made the car idls smoother and got rid of a flat spot .

They are a part which wears over time- copper is the best you'll get for "performance" as it conducts better than iridium/whateronium they use in the big dollar plugs.

It makes sense to use them for the average person - why get something you need to replace every 25thou when these will last 100?

To be blunt its a bit of a marketing win - the internet thinks iridium will give you more power - it won't, it can't, a spark is a spark - and I believe they get effed up a bit using avgas etc (bit more touchy) where copper won't. BUT the marketing is correct in that they'll last longer, and for 99% of users that's the main thing. I'm in the habit of whipping plugs out to check condition with every oil change / bored sunday etc anyway so quite happy to just replace them each time if they need it, but for Mavis who doesn't even know where the bonnet catch is it's a slightly different scenario.

Same theory as the long-life lightbulbs I suppose? I'm a cheap bastard who can't cope with $30 a bulb, even though I know it'll be cheaper in the long run - it's easier to swallow $5 once a year or so.
