I installed my WeaponX coils this afternoon and I have to say that first impressions are very good.
It definitely starts a bit sharper and idles smoother. Off-idle to low speed, you don't feel like someone slipped a supercharger under the hood, it simply feels a bit stronger and smoother. However, under heavier throttle I am absolutely pulling much stronger. But again, more smoothly as well. The engine feels like it has more of a sweet spot, and the throttle response is better.
I have the Blizzaks on due to today's weather, so I can't compare if my cruising RPMs have changed like others have reported.
There is one thing that has me a bit perplexed... Some of the raspiness is gone from the exhaust. My car has never had a fart-can sound, but there was definitely a buzz when approaching 3500 to 4000. Most of that buzz is gone and the exhaust is fuller and deeper in tone. Same goes for revving when in park. Whatever it is, I'm good with.
I topped-off the tank so I can start getting a few of those going to see how MPG might change.
Very happy with the $ spent and apparent benefits. And like the headers, if it prevents problems from a common V6 issue down the road, even better.
A couple of things not in the instructions, but I'll recommend doing anyway:
-They don't say to do so, but I put a dab of dielectric grease inside each tip and boot on install. I also put a very, very light film on each cylinder seal before sliding it down into the opening. Should help seal the chamber as well as keep the seal from sticking.
-The instructions stress how difficult it will be to 'snap' the coils down onto the plug. What I did was use a dual-face hammer and tapped each coil lightly two or three times with the soft-face. There was a definite difference in how secure the plug felt afterward. The nice thing about the hammer is you're hitting the rim of the coil body and not the section over the electronics.
Day Two:
There is more power. I'm not ignoring what is an obvious improvement in throttle response, but there is additional power down low as well.
The change in exhaust tone is odd. Cruising at 70 on the highway the car is noticeably quieter. Even some of the off-idle burble is gone. And that's fine with me. Last thing I want my car to sound like is someone who thinks his V6 Mazda is a V8 Mustang.
---edit---
They cost me $329 plus shipping.
