EHS Racing Yamaha Grizzly 700 Airbox Review

When you are adding aftermarket accessories like a better flowing exhaust or performing any kind of fuel delivery modifications like a jet kit or using a fuel map programmer if it’s an EFI machine, it is almost a must to let as much air as you can in.

The only way to do that is by the addition of better flowing aftermarket air filter such as those that are readily available at most of your ATV / power sports retailers. Well Eric Sutton owner of EHS Racing has taken this a step further with his custom modified air box lids.

We ordered two lids, one for the 2003 Rincon we use for some testing and will be reviewed in another segment sometime next month and another for the 2007 XTG (Extreme Terrain Grizzly 700). You can purchase it as a kit and modify your air box cover or you can spend just a couple more dollars and receive a new cover completely modified and ready for installation. Plug and play!

<table style="height: 100%; text-align: left; margin-left: 0px; margin-right: 0px;" border="0" cellpadding="2" cellspacing="2"><tbody><tr><td style="text-align: justify;"> The air box lids arrived just in time for our trip to Southern West Virginia's Hatfield and McCoy Trailfest. After a quick inspection from everyone in our entire group like it was a newborn baby it was time to install the air box on the Grizzly 700. Installation was a snap and the instructions provided were very easy to comprehend. Since these are merely modified with the OEM air box covers the fit was perfect. The aluminum plate, which surrounds the water resistant Outerwears fabric, is custom CNC milled for exact precision with the EHS Racing Logo engraved on it.
Upon ride testing we noticed a nice mid range power increase. It is really hard to tell from our “seat of the pants dyno” but we could tell a slight difference in performance. The real gain though is in the protection it added to the air filtration on our Grizzly 700. The Grizzly 700 system in our opinion has an extremely poor air filter setup. If not properly installed the stock setup will allow dust and dirt to get past the air filter itself causing damaging harm to your engine. The EHS Racing lid along with the custom plug for the boxes intake hole acted as a pre-filter during our riding in the extremely dusty conditions. We had tested this system against 2 other grizzly 700’s that weekend and both machines required their air filters to be cleaned every night after returning back to the camp. My Grizzly with the EHS Racing lid did not require a single cleaning during our entire trip.
<table style="height: 100%; text-align: left; margin-left: 0px; margin-right: 0px;" border="0" cellpadding="2" cellspacing="2"><tbody><tr><td>
</td><td style="text-align: justify;">The only downside we could see in this system is that is could have the possibility to allow water in the air box. I personally did not think that this was a big concern for the Grizzly 700 due to it's high airbox location, but other machines may be affected by this.
In summary the EHS Racing custom air box cover is an excellent add on that will add both performance as well as protection for your investment. For anybody wanting to improve their airflow as well as increase their engines air filtration efficiency, take a serious look at this lid. You won't be disappointed. Give Eric at EHS Racing a call! He's a great guy to work with and offers a 100% satisfaction guarantee!
