80% of the job is moving the intercoolers out of the way and mounting them. The rest is pretty easy. Make sure to torque to the specs listed in the FSM.

Well now...

I mean outside of it not being OEM for warranty purposes its a non-issue, you get way more benefit of having a correctly gapped spark plug and the correct material (iridium and hot/cold design) being the biggest factors rather than it being a single or twin tip design. Since he is tuned running colder plugs makes sense in this application.


Probably a good read on the subject matter of hot/cold plugs.

But those spark plugs are not colder than the OEM ones as there the same exact heat range of 8.

How do you like working with Z1 on the tune? Would you recommend?

Z1 is phenomenal. Great customer service and super friendly. Fast shipping and great product support. They’re not always the cheapest (always priced well though) and if there are any issues there’s no need to worry. Been doing business with them for 20+ years.

Jon (the owner) has been tuning my car. He always provides great feedback and assurance that my car is in the best hands. The tune is strong!

It’s not difficult. Just takes some time and patience. I’ve removed them a number of times already so I have the system down. The more you perform the task the easier it is, just like anything else 👍

The hardest part is mating the intercooler to the 2.75” coupler leading to the throttle body. Once that’s done you connect the other end to the coupler leaving the turbo. Finally, you connect the 4 bolts that secure the intercooler and tighten up the 3 hose clamps. 2 between intercooler and throttle body. 1 coming from turbo to the intercooler.

If I forgot to mention it - @Boxy prescribed these plugs be gapped to 0.024

Heat ranges for spark plugs are not universal, an 8 heat range for an NKG plug doesn't equate to another. But you are correct they are the same heat range which is a bit odd.

Gapped to 0.030. That’s what my stock plugs were gapped to. Is it worth the effort to repeat the job?

Kinda off topic, but has anyone heard of NGK's new spark plug lately?
Ruthenium?

Is this something that is compatible with our VR30?

Just looked at these and emailed NGK since they don't list a compatible plug for the VR30DDTT. Per their Lead Technical Service Rep, The LKAR8BHX Ruthenium plugs are identical in spec to the OEM DILKAR8K8G Laser Iridium plugs making them interchangeable. I plan on trying these when I change mine (probably in the next couple weeks).

Bump - Anyone have some input? 6 thousandths of an inch... It takes about 2 hours to do the job.

What boost pressure are you seeing?

 

[Kraken]

Peak 20psi, levels out at 18psi

 

[Turbonut]

I'd go lower. If anywhere @ the 15 psi, I'd leave it there, but up to 20, I'd say it's borderline, hit or miss.
You could always leave it and if there is a misfire then bring it tighter.

I'm gonna ask you this down the road. Remember the answer. 😁 My organizational skills are ****.

Eff it. For 2 hours of work I’m not going to risk it. Will get it knocked out tomorrow. @Boxy’s a very reputable resource on this platform so I’m gonna follow his instructions to the “T”. Thanks @Turbonut 👍

Wow,,that is EXCELLENT INFO ON SPARKPLUGS!

Supposedly it's inferior to the "best" iridium ones. I remember reading a while back, the Ruthenium marketing claims are somewhat deceiving to make it seem it was a "superior" alternative to iridium type spark plugs when they are comparing it to the lowest tier Iridium spark plugs.

Some actual testing could prove otherwise, I thought it was an interesting take.

I think it's hard to beat the Denso or NGK laser iridium spark plugs, provided you don't need a hotter/colder unit.

 

[Brianq50sport]

My neighbor gave me a set of the laser iridium plugs after his Q50 was flood totalled and I installed them in my sons G37, they seemed to be excellent, and I am driving with the autolite iridium xp in my Q and everything seems a- ok
