I installed these in a Ford F150, and it starts more smoothly now. The engine sounds like it runs better. I like the strong warranty which gives me confidence that I won't have to replace these again for quite a while. It wasn't a hard installation though!

These coil packs were easy to install and work as well or better than the originals.. The downside was that they said they fit a 4.6L Ford motor but did not specify what year. But after some modification they still worked on my car. Now the car runs better than it did before! Unfortunately the spark plugs would not fit my engine because these are for a later model 4.6L engine.

Ordered this (8) Pack of High Performance Straight Boot Ignition Coils & Spark Plug SP546 - 15% More Energy For my 2006 Ford F-150 truck. I purchased this truck back in late spring and been reconditioning it inside and out, and getting it ready for not only fall & winter months, but will be using it full time in my trenching business. Overall truck runs good with 44K miles on it, but noticed while in drive and sitting at a stop light or four way that it seems to vibrate like. I recently took it for new tires and I ask shop mechanic about it and he advised that it was probably a bad plug or coil not firing correctly.Also ask my neighbor mechanic and he mentioned same problem. Since then, I have been replacing sensors, and etc. as it's 18 yrs old. While recently shopping online for air filter, and other parts for the old Ford, I saw this complete high performance kit/package of new coils and new iridium high performance spark plugs that fits my truck. After reading about them and their performance,I ordered them. Right out of the box, you can see that these are quality made and designed replacements. I wanted to get the coils to replace with plugs as it's the right time when having to remove the plugs. My neighbor mechanic advised me to "blow out the plug hole area" before removing plugs in case of any dirt, dust, or debris can fall right into cylinders, So I took my time and changed them all out and installed the new coils as I went. After finishing, I started my truck up and then drove it.It runs like a brand new truck!. Actually can tell it has more power and "no more vibration". So I'm unsure which one was the problem, but now it's fixed and running correctly and engine is tuned up good and should last me many miles. They also come with a (5) year warranty and that alone gives me peace of mind. Happy with order

After a few decades my truck just wasn't running as well as it should have, honestly I wasn't keeping up with the normal maintenance like I should have. After finally doing something about it, I replaced all the usual stuff and then focused on the fuel system. I replaced these last and they sure have made a difference. My truck runs like new again, I can highly recommend this as part of your tune up if you need to do one as badly as I did.

These coils and plugs are extremely easy to install I don’t notice a huge power difference in my 08 f150 they seem like a good value and seem well made

So purchasing a 08 F150 I am aware of the problems Ford had with the spark plugs and anything previous to the 2010 models. With that being said, I thought I would go ahead and make sure that I was prepared in case buying a used truck someone had not done the coil and spark plugs before me. my preferred brands were Denso along with Ohio Tech however, I went ahead and chose the BraveX brand. So far so good, I see the color of who they tried to copy and that’s OK I’ve only been running these for a couple of weeks and so far I have not had any issues nor did I beforehand. I have not had a chance to hook it up to a code reader however, as of right now there’s no need. I am keeping my others just in case but so far it’s been a smooth run

well the product was nice but unfortunately it didn't fit my vehicle with it being the boots that are curved i reached out to support to see if there is any way to get this fixed i even sent a email because one of their statements are customer satisfaction where i couldn't even get a response and guarantee to customers need
