Spark plug NGK or Denso

I've decided to install the plugs myself. Given that the vehicle has nothing in the way of a tune, it would seem that the 'standard' heat range plug would be the best fit. APR does not seem to offer a 'standard' heat range plug so they are off the table. The prices for the NGK plugs from the dealer seem reasonable even there challenge is 'which one?' They list a 06K905601B Type 1 and a 06K905601L Type 2. Google searches offer nothing in the way of information about the difference. Is it the heat range? the external construction? the internal construction? the ???. There is a price difference in that the Type 2 is over twice the price of the Type 1 so I am assuming there is some difference, but no specifications to suggest what. To ensure theMuffinMan understands what I am saying ... I am not sensitive to the price difference BUT it is the only factual piece of information I've been able to find, other that part number, to distinguish one from the other. I am stating the difference as a fact and not as part of the selection criteria. Looking at the NGK offerings, they seem to be NGK PLFER7A8EG Laser Platinum or NGK LFER7BHX Ruthenium HX. Any insight would be appreciated.

NGK (who makes the VW ones) offers upgraded Ruthenium HX ones for less money (NGK-supplied VW ones), with improved performance and longevity compared to their aftermarket Iridium-IX ones.

Currently using the NGK racing R7438-8 (NGK 4905)

I have eqt and the densos and they are smooth

Ruthenium HX 95125. Lots of good feedback on the forums, I’m using them out of the box gap and they’ve been great. About 5K miles so far

From literally every single objective comparison, the NGK ILKR9Q7G looks like be identical to the HKS M45XL except for price. NGK literally produces the plugs for HKS and NGK is likely the largest plug manufacture in the world with decades of reliable products to boot.

Mine are either ACDelco or NGK, cant remember which. Either way no complaints.

Denso IKh024

I've used Autolite plugs in my stock 2011 for 6 years. I wanted to try NGK's so I recently installed a set of Ruthenium NGK plugs. I haven't noticed any difference between the two brands.

the densos work fine, the point of swapping is not for any performance gain, rather to prevent shattered ceramic from raining into your cylinders
