Bosch plat +4's work good for stock engines.. I have magnecore 8mm (blue) wires, havent had any problems.

I ask because I did the wires in my Rover 2 weeks ago and it took an entire day and some really banged up hands.

Turns out I was supposed to remove the intake plenum from the engine. Really great design.

It's super easy. So are the plugs, just have to unscrew the coolant res to get to the last one on the r side.

did not notice any increase in mileage, but I believe that's caused by heavier right foot.

The drawback is they are WAY more expensive than +4's... so it's not for everyone.

Next time I do it, I had considered getting the Denso plugs, if they actually seemed to be worth the money; it is often hard to tell.

I donno why but my +4's have rougher idle than oem and denso.

I don't remember the throttle response nor the mileage though...

if OEM is no worse? Is it because it's not time to change the plugs back to OEM? I'm new at this plugs business, so am trying to learn...

I didn't bother take them out again, buy a set of oem's and reinstall.

Ditto on the Bosch wires.. My OEM's burned out and the Bosches haven't thrown codes or done anything wierd yet..(3K miles)..


I'd do that. About 150-175 over the 325 for oem set...
