spark plugs

[huntersmob]

hello I'm planning to do the spark plugs over the Christmas period,
can anyone recommend what's best to use, the dealers want £18 per plug euro are advertising 2 types of denso is one iridium ?

thanks in advance

get the Bosch ones code 408778900 on Euro Car Parts

£54.95 for 10 if you use discount code BLACKFRIDAY before it ends this weekend

bargain

I was just wondering if the expensive denso ones would last longer

bosch ordered plus spare oil at half price

well I have fitted the spark plugs over the xmas break and cannot see why audi would want to charge £787. I took my time and in all it took about 3 hrs including cleaning and re oiling the itg filters the worst two plugs are the ones near the bulkhead as you have to remove a few electric connectors etc and turn the coils to get them out .
I would recommend anyone doing the job but do it on a summers day

we use (modified stage 2 plus);

DENSO IK01-24

or NGK

R7434-8

Both have the better electrode design, which reduces the chance of det damage and is a few heat ranges cooler.

STD setups or stage one:

DENSO IK01-22

or NGK

R7434-7

Better tip design but only one heat range cooler.

@huntersmob the denso plugs are of better build and quality generally as for life span i cant say.
