Bosch rep told me over the phone there will be no more, they’re extinct.
I just received the last set in original Porsche box from an eBay vendor 😅
When I replaced my plugs in 2018 I used the blue box Bosch Y5DDC like so many on rennlist- around $8 a plug 😂
There’s a slight difference but the ones in the Porsche box cost 3 or 4 times the price-
I’d like to see what the BMW version of the Y5DDC looked like-
What a battle to get these 🤦♂️
I paid $123 which included shipping from CA and tax
Most dealers have them for around $27, and as mentioned I’d go in person or call to make sure they do indeed have them-
So the Brisk rep wrote me back, here's what he said:"The BOR14LGS design I think would be a plug option but ultimately, I don't think it would be the top recommendation purely based on the spark plug gap requirement by the GT3 platform. They require a pretty tight gap specification which is right around the effective gap of the LGS design. As the plug wears the gap could potentially become too large and out of spec and it could result in a misfire.
For the GT3 platform NGK references their factory heat range as a NGK 8 - cross referencing the Y5DDC to other brands such as Denso they reference a NGK 7 heat range as well as an NGK 8 also. I believe that it would be better to go with the colder of the two personally.
For a stock platform GT3 in these year ranges our top recommendation for a street plug would be our Brisk Premium EVO BR12BFXC.
For a stock platform GT3 for a race spark plug, our top recommendation would be our Brisk Silver Racing BR12S. The Brisk BR12S utilizes a non-projected insulator tip configuration that would benefit your application during heavy duty cycles as it combats knock more effectively which would keep the ECU from pulling timing, especially when heat soak becomes a factor."
So most of the plugs that came in the Bosch box had blue stripes on the porcelain, and the tips were different than the one on the left. But, as the years went by, the Bosch boxed ones were also showing up with green stripes, and the different tip. They all worked, but it's good to keep it in perspective:
Colder is better if one were to error on caution. For the longest time, I was confused on NGK I admit. US is different than JP. Worked I guess in my favor for 250r (TRX) hi-comp builds.
Really comes down to aggressiveness. But I’d give Porsche sometime to source another supplier. The Evo is a good recommendation, but you have to drive equally as aggressive. That’s the dilemma for some.
It's every 24K miles or four years. 4 years I suppose in case the threads get caked with oil/turns into carbon which could make them difficult to remove.
I replaced my original plugs 7 years after the car was built, and it had lower than average mileage. No issues removing the original plugs, and they had a healthy tan, and usual normal oil residue on the threads.
It would be interesting to see what BBI, Sharkwers, Dundon and other performance shops have to say about plugs, and I suspect sooner or later there will be a lot of people searching for plug options-
I'd also like to know what the heat range of the CUP NGK plug is-
Oh ok. Got it. I might have seen something else for track usage or the 996/997 cups. Though, it seems you could extend the interval based upon your observations. Usage certainly has a part to play as well as what fuel you get at the pump for the DE.
if you still need someone to call that shop on the bottom of page 3, I can do it.

Just to confirm, when Bosch pulled the pin on the Y5DDC they also pulled the pin on the Porsche OEM plugs too? Does this mean Porsche are out of plugs for our cars too for the moment whilst they source an alternative?
I see a price of $547.86 after $50 "Heatwave" discount.
Agh, my bad. Either I got one of the last sets on "clearance" or the price switched over after Sunday. With CA tax, free shipping and HEATWAVE, I paid $397.62. I'll keep an eye on FCP.
The Bosch rep said no more, including the special dealer ones on Porsche boxes. BMW E36 M3 cars also used the Y5DDC and now need alternatives.
The NGK link I posted shows only that plug, which is 1 step colder than the Y5DDC, and has 2 ground electrodes just like the Bosch. However, other crossover chart sites have other modern NGKs, and the heat range is 7, which in NGK is equivalent to Bosch heat range 5.
There are 2 spark plug threads going on in the forum, I've tried to post all the findings on both threads.
It would be nice if someone could speak to a major dealer about this, and if BBI, Sharkwerks, Dundon and other performance shops could offer their opinions-
There are 12 NGK plugs listed, and they're all heat range 7.
But, as posted before, the NGK site only lists the DCPR8EKC as the plug for Mezger GT3 cars.
With so many plugs offered, NGK's own site doesn't seem to offer enough info and options.
And if they made a DCPPR7EKC to match the Y5DCC heat range it would be perfect, but they don't.
Here's a close-up pic of the Brisk, it has 6 ground electrodes(!)
