Nice bundle for my 2011 Charger 3.6L
I recently replaced my coil packs and plugs and was happy with them but decided I would give these a try for the sake of testing, since I was replacing my lower intake anyway.
The seals that come with this bundle are the same fit, color/material as the last kit, and they fit the grooves nicely and don‘t fall out. The plugs were not gapped properly, but that’s why we should always check and adjust every plug, which was easy enough.
The coil packs also fit great and, while this doesn‘t really matter, they look cool too (sorry, forgot to take pictures).
Post-install, the car fired right up and purred like a kitten as expected.
Overall, this has been a great bundle for my Charger. I’ll update my review after some significant mileage is put on the parts and/or if I run in to any issues and don‘t worry, the old (barely used) parts are stored for future use!

2023 tacoma cold air intake.
Put the cold air intake on my 23 tacoma. It has added a noticeable amount of mid range HP and makes the truck sound great as well. If you own a gen 3 tacoma you know the mid range power can be laggy. This intake system is well worth the purchase would recommend it. It also looks great and seems my fuel economy has gotten better because the motor has to work less getting up to speeds. Would recommend 5/5.

Mystery boxes
I ordered the $20.00 and the $50.00 mystery boxes and i REALLY wish i would've waited to order the prior orders that i had done through Amazon.
I got the black braided fuel line with a BUNCH of AN fittings. Well, that is exactly what i had ordered before, but i had gotten the stainless braided line before and the mystery box saved me a bunch of money. Lol!
The other mystery box i ordered has the black 750 ml catch can. Well, that is exactly what i had ordered before except the one prior is the silverish look and yes, i spent less on the mystery box. Lol! Smdh.
The quality is great.
Shipping for me always takes way longer than most due to living way out in the middle of the Pacific Ocean, Maui. But, I can't blame you guys for that.
I am very happy with the stuff and what i don't use will go to my neighbor who is also upgrading his ride.
My corvette will be making some sweet LS muscle music very soon.
Thank you, Evil Energy!
