Replaced stock with denso ihk24.
denso ik22 works also, also an iridium tipped plug
I bought a box of denso.
Everyone has been praising (fleet vehicles).
Bosch components made in the EU (this is the important part) are in many cases the items that VW installed on the car in the plant, or better. Take the spark plugs for example, Bosch just prints the VW name on it and VW installs it in the engine.
I have just replaced the oil and all 6 spark plugs with Bosch Double iridium.
As for the spark plugs, both Bosch Iridium and NGK Laser Iridiums are fine, arguably even better than OEM (which are made by Denso, btw).
Im with the Densos already and the spool and throttle response is so much better. Even with gap 0.075mm they are much better.
But otherwise, Bosch FLR8LDCU+.
God knows they can only be as bad as the Bosch plat +4's, Man those are terrible in basically everything I've put them in... good luck!
Had bad bosh plugs before.
Never had a issue with OEM ac-delco or Ford plugs/parts.
