Smoother drive at highway speeds. Faster starts. Improved MPG.

Cost to much for what it delivers. All the mentioned strengths had very little positive gains.

Very easy to install. Instructions come with Honda/Acura installation instructions, every other car model has to figure out the basic installation for there cars.

The comments are based on using MSD-SCI, MSD Blaster SS, MSD 8.5 wires, and distributor cap modified with MSD Power Tower.

It stopped flooding of my engine since it burns all the gas away. Didn't feel other difference though. Noticed a few more miles per full tank.

Car does not push start anymore. When u touch your spark plug wires, becareful since it might shock you. Buzzing sound comes from discharge module (mounted under driver seat).

Overall, i think that this product is great for turbocharged vehicles. The whole purpose of the MSD is to increase the spark to burn off the extra fuel added in the combustion chambers. Obviously it is useless if you haven't done any serious upgrades to your engine to increase the fuel delivery.

Looks good.

Off road unit quit working after less than 18 months. MSD factory tried to sell me another but refused. Had same problem several years ago with 6A unit on 86 chev. When unit on truck died had to call a wrecker to get me off the street as was pulling large trailer. MSD wouldn't pick up that tab when asked.

Not worth the cost. Not reliable. Does not really improve anything if you have a good ignition system on vehicle already. Spend your money on other items ie; good intake filter, exhaust system etc.

Crane unit back on truck and works as good or better than MSD. At least this one is still working after more than 8 years use. (Unit was on 89 truck and then reinstalled on 97 after MSD unit died.)

Came complete and I did not need any other parts to make it work.
It also had a nice constuction.It improved the power band and made motor
feel sorta like a honda V TEC.

Manual was more directed towards domestics. Not very import frienly,I had problems finding space to mount IG box.
Main power wire is too short, It also is a little on the heavy side and draws too much current from charging system .The MINI SS blaster runs too hot.

I perchased MSD 6a box , blaster 2 import coil and ACCEL wires as complete IG upgrade , i hve had a lot of starting problems, (long duration crancking )Especially when cold. All this maybe becuase of shorter intake pipe between hot wire MAS air flow meter and throttle body .But i understand that this is a performance upgrade and any drift from OEM can alter driverbility , Overall though it was worth the money since I will be going turbo. I don't really recommend this product for small imports unless these cars are highly modified ( turbo/nitrous/head work ect.)I would only recomend this product for the larger displacement crowd and anyone looking for a little more MPG and pep.

Wittnessed it used in domestic big blocks ,(mustang,dodge,and DRAG cars).

Installed MSD6a and blaster coil used for 100,000 mi and verified performance by bypassing MSD Box three times.

Benefits are: Instant Starting, soother idle and noticeable increase in toque and power. Plugs stay cleaner but ware out sooner, and mileage went from 23mpg to 28mpg freeway and 16 mpg to 17.5 mpg average.

Without MSD BOX timing feels retarded and performance and MPG are noticeably less.

Also tried units on an air-cooled Porsche and 944. Noticed an increase in performance on both vehicles but only when used with MSD coil.

Large size can be difficult to mount.

Difficult or impossible to install on Distributor-less systems.

Spark plugs, Distributor cap and wires can erode quickly (a problem on the BMW as a dist. cap is over $100).

When starting system can set off home and auto alarms for some distance.

Not sure, but it may have damaged the computer in my 944

Also, it can cause an excess build-up of ozone in distributor caps causing rough running and stalling.

experenced some drivability problems with 911 Porche due to dist. cap arcing.

A Well engineered and constructed system. I love what it did for the BMW and would definitely recommend it.

However gains might not be as noticable on all vehicles, and as with most aftermarket stuff there can be the potential for problems and it's not allways a simple plug-in installation.

Wish they made a plug-in set-up for my Expedition's DIS system.

solved alot of idling problems and MPG went way up. (I ws running 18 MPG in city and went to 28 MPG) best now is 32 mpg on highway cruise. I also dynoed before and after and can verify 3-5 HP across the board and 7-9 HP from 5500 RPM to 6400 RPM redline.

trying to find a place to mount it.

$360 but that could be cheaper if you shop around. I bought it with a pre-made wiring harness which made installation a snap. I would NOT recommend if all you have is a header,intake and exhaust as I think you will be disappointed with results like the people above. Now if you plan on motor work (like I have done) or NOS or turbo/supercharger then it is a must.

stock whic is fine until you have a ported and polished head, cat bgack and high flow cat and overbored TB and CAI and then resetting computer which means it gives to much fuel at idle which does not get burnt righ and that is why I think I saw so much HP and MPG improvement

MSD-5A. Compact size, relatively easy installation with optional cable for my '92 Ford Bronco; cured occasional pinging problem (couldn't cure originally, even with premium fuel)

Died after a few years use; truck started failing while driving; plugged original ignition back in, bypassing MSD, & truck runs fine; didn't see ANY mileage or power increase (like magazines claim)

Paid approx. $300Cdn for this unit. Didn't realize I could buy it for MUCH less via mail order. Didn't like that it died after only a few years, & haven't looked @ replacing it 'cause of the expense.

Unit looks good
compact, fits in tight space
All wiring and connector are included, you wont need to buy anything else to get it going
Good tech support via the web
Felt an extremely minor power gain, or rather a quicker throttle response

Instructions were VERY vague and misleading. If you dont know anything about ignitions (like me) you are going to spend the weekend installing this thing. The instructions are written for seasoned mechanics, they assume you already know what you are doing.
Very minor gains, if any at all.

I paid $185.00 + shipping from jegs.com. I guess the price is OK for what you get, not a big power increase at all. They need to work on the documentation a lot, though. They give you directions for basically ALL Hondas with only 1 illustration. I would recommend buying this mod LAST...spend the money on a header, intake, exhaust, cam, supercharger, etc...You wont notice this upgrade much, in fact I have almost forgotten it was in there. The only reminder is that wasted Saturday and Sunday it took me to install it.

Noticeably quicker throttle response, smog legal in all states, easy to connect, can be integrated with future upgrades.

None.

Installation was simple, other than finding a place to mount the unit(I finally found a space under the battery tray on the fender well for a homemade mounting plate). Diagrams easy to follow, integrates with stock tachometer, and noticeable performance improvement. An excellent upgrade.

The car seems to run smoother and quicker response.

None to this date.

$179. I would recommend it for force induction applications.
