Fitted these today and my word they make a difference.
i. Smoother idle
ii. much perkier at the top of the rev range
Okada quote the following for these coilpacks....
i. Up to 6% more hp
ii. Up to 6% more torque
iii. Faster spool up/throttle response
iv. Reduced fuel consumption
v. Lower emissions
vi. smoother idle
Also in the 1.4TSI they help eliminate potential misfires too by giving a much stronger spark that simply cannot be overwhelmed by the injectors.
I fitted them myself in 15 mins and they just work!
I'll be swapping back to the stock coilpacks at some point for back to back dyno runs to see if they do give any extra oomph, but the car certainly feels better and it isn't just the "bum dyno"
They aren't cheap though, but for me they are worth every penny.
Maybe after I get the oil consumption sorted and I've had a Milltek TBE fitted I'll go for some of these. Will be keen to see the back to back dyno runs
